Super PAC supporting Hillary says it 'will not make the same mistake' as the GOP and ignore The Donald: We take the threat of a Trump presidency seriously 

In a new memo, Hillary Clinton's super PAC is needling Republicans for underestimating the GOP frontrunner while reassuring supporters that 'the threat of a Donald Trump presidency' is being taken 'seriously' 

'The political malpractice committed by the Republicans when it comes to Donald Trump was avoidable and Priorities will not make the same mistake,' wrote Priorities USA Action's Co-Chairman and Chief Strategist Guy Cecil in a public memo dated today. 

'You can't ignore Donald Trump, you can't hope someone else will take care of him, and you can't beat him by becoming him (sorry Marco),' Cecil said.  

Cecil, listed as someone in Clinton's 'inner circle' by Influencer16.com, said the super PAC, which Clinton inherited from President Obama, has been readying to go up against Trump since last summer, when the billionaire announced his unconventional bid.

The Hillary Clinton-aligned Super PAC Priorities USA Action said the Republicans committed 'political malpractice' for not going up against Donald Trump - and that it wouldn't be making the same mistake 

Priorities USA Action plans to hit Donald Trump (pictured) on his 'business record, temperament, and penchant for sexism and racism' 

'His business record, temperament, and penchant for sexism and racism are out of step with most Americans and we will be prepared to take that fight to him,' Cecil wrote. 

'Donald Trump has selfishly championed his own interests at the expense of everyone around him – workers, women, and people of color, just to name a few,' the Clinton insider continued.  

'He has repeatedly made sexist and offensive comments about women, and has a history of flying off the handle, which isn't the temperament we need in a commander in chief,' Cecil added. 

The Super PAC is also there to spend money on Clinton's bid – though not conjunction with her campaign, of course – but Cecil warned of simply just throwing money at the problem.   

'As part of that commitment, we will distinguish ourselves from Republican Super PACs by making smart, targeted investments, and taking the threat of a Donald Trump presidency seriously,' he wrote. 

Cecil also discussed the role that Super PACs have in the bigger picture of the campaign, pointing to failed bids – like that of Jeb Bush – where the Super PAC essentially was the campaign. 

'If there’s one lesson to be learned during this primary season, it’s that Super PACs can’t replace good campaigns, but they can support and enhance them,' he said. 

On the Clinton campaign side of things, Bill Clinton reportedly also views Trump as a big threat. 

He was among those advising his wife's campaign who suggested a run against the Republican frontrunner  would be no cake walk.

Bill Clinton 'dismissed those conclusions as denial,' wrote the New York Times, in a story outlining the former secretary of state's general election strategy, which plans to focus on many of the same issues that could be problematic for Trump.

Donald Trump is not your typical presidential candidate and so the Clinton campaign is trying to figure out how exactly to beat him in the general elections if both campaigns succeed 

She'll have the challenge of running against a non-traditional political outsider who bested 16 other Republicans in a year where the electorate is angry and ready for change while being one of the most familiar names in politics for more than two decades.    

'Hillary has built a large tanker ship, and she's about to confront Somali pirates,' Matthew Dowd, the former chief strategist to President George W. Bush's 2004 campaign told the Times, of the candidates' two different styles and operations. 

That's where Bill Clinton comes is as he'll be deployed to be the mouth that takes on Trump.   

Letting Bill Clinton off the leash will help suck up some of the air time from Trump, who has excelled at dominating the election news cycles.

Trump, this week, laughed at Clintonland's plans to label him as a misogynist, one of several attack lines the Clintons are expected to deploy.

'If Bill tries to portray me as a sexist, he's going to have a hard time,' Trump said on Fox & Friends.

The Republican has already had no qualms with bringing up Bill Clinton's sex scandals from the '90s and hinted that he would do so again. 

Dowd also warned of this problem in contrasting the styles of Clinton and Trump. 

'Can you imagine what he'll do?' Dowd mused. She will bring up equal pay for women and abortion rights, he told the Times, 'and [Trump will] turn to her and say, 'You can't even handle your stuff at home.'' 

But Clinton has another powerful surrogate in her pocket – the sitting President Barack Obama. 

Obama, according to the Times report, 'has told allies he would gleefully portray Mr. Trump as incapable of handling the duties of the Oval Office.' 

It was Obama, too, NBC's Chuck Todd pointed out last week, who's had the most luck against Trump and it was in one of the most unlikeliest of venues. 

Nearly five years ago, in front of an audience of thousands and C-SPAN's viewers at home, Obama mocked Trump at the podium of the White House Correspondents' Association dinner. 

Trump had been beating the birther drum, suggesting that President Obama had been born in his father's home country of Kenya, instead of in the United States in Hawaii like he was. 

The Donald had also been testing the waters thinking of launching a 2012 presidential bid and was invited by the Washington Post to attend the 2011 dinner.  

Obama, who had been forced to publicly release his long-form birth certificate, suggested that Trump was happy to put the issue behind them.  

President Obama took on Donald Trump in a memorable White House Correspondents' dinner roast. 'Ultimately you didn't blame Lil Jon or Meat Loaf, you fired Gary Busey,' Obama said.  'And these are the kinds of decisions that would keep me up at night' 

Ted Cruz tried to execute a similar line against Donald Trump mocking his reality show past at the last Republican debate in Houston, but the attempt fell flat 

'And that’s because he can finally get back to focusing on the issues that matter: Like, did we fake the moon landing? What really happened in Roswell? And where are Biggie and Tupac?' Obama mused.  

'All kidding aside,' the president continued. 'Obviously we all know about your credentials and breadth of experience.' 

Obama then detailed a recent episode of Celebrity Apprentice in which the men's cooking team did not impress the judges from Omaha Steaks. 

'And there was a lot of blame to go around,' Obama noted. 'But you, Mr. Trump, recognized that the real problem was a lack of leadership, and so ultimately you didn't blame Lil Jon or Meat Loaf, you fired Gary Busey.' 

'And these are the kinds of decisions that would keep me up at night,' the president smugly added.  

While the comedy act seemingly dashed Trump's presidential hopes that cycle, when Ted Cruz, who won three states in last night's Super Tuesday primaries, deployed a similar attack at the GOP debate last week in Houston, it fell flat.

That could signal that not even a good line could down The Donald.

'I really find it amazing that Donald believes that he is the one who discovered the issue of illegal immigration,' Cruz began. 'I can tell you, when I ran for Senate here in the state of Texas, I ran promising to lead the fight against amnesty promising to fight to build a wall.' 

'And in 2013, when I was fighting against the "Gang of Eight" amnesty bill, where was Donald?' Cruz asked the debate audience. 

'He was firing Dennis Rodman on Celebrity Apprentice.'
