Even Bernie doesn't think he's a Democrat says Hillary in desperate bid to get party loyalists behind her after Sanders wins AGAIN in Wisconsin 

With a convincing win last night in Wisconsin, Vermont Sen. Bernie Sanders continued to deny frontunner Hillary Clinton the claim of the Democratic nomination. 

So in order to push back, Clinton has been questioning Sanders' Democratic bona fides. 

'Well, I think he himself doesn't consider himself to be a Democrat,' Clinton said today on Morning Joe. 'And, look, he raised a lot of important issues that the Democratic party agrees with, first and foremost, but it's up to the Democratic primary voters to make that assessment.'   

Clinton has become more vocal in exposing Sanders' nebulous party affiliation in recent days. after the self-described democratic socialist senator expressed uncertainty when asked if he would raise money for down-ballot Democrats as the party wages a battle to take back the U.S. Senate from Republicans who gained control in 2014.

He doesn't even go here: Hillary Clinton, when prompted, questioned Bernie Sanders' Democratic bona fides as he routed her from the nomination once again last night in Wisconsin 

Hillary Clinton appeared on Morning Joe today and suggested that Bernie Sanders' embarrassing New York Daily News interview showed that he didn't do his 'homework' for the past year 

When asked by Politico's Glenn Thrush about Sanders being a 'real Democrat,' she responded, 'Well, I can't answer that.'  

She then smiled and answered that. 

'He's a relatively new Democrat, and, in fact, I'm not even sure he is one. He's running as one. So I don't know quite how to characterize him,' Clinton said. 

Today she expanded on those comments by committing to help Senate Democratic candidates win their races. 

'I've been in the trenches a long time and I believe in electing Democrats up and down the ticket,' she said. 

'I want to see the United States Senate move back in Democratic hands with my friend Chuck Schumer as the majority leader,' she said, giving a shout-out to the prominent  New Yorker as she turns her attention to winning the Empire State.

'So I'm going to keep working and fighting for all Democrats,' she added.  

This morning's appearance on Morning Joe was also Clinton's first opportunity to swing at Sanders for his questionable interview with the New York Daily News' editorial board, in which he was unable to easily articulate how he would break up the big banks – one of his main stump speech prescriptions.

Clinton wouldn't give a straight yes or no answer when asked repeatedly by Scarborough whether Sanders was 'qualified' to be president.  

Sen. Bernie Sanders moved on to Wyoming last night - which holds its caucus on Saturday - to celebrate his big win over Hillary Clinton in Wisconsin last night 

'Well, I think the interview raised a lot of serious questions,' Clinton replied. 'And I look at it this way, the core of his campaign has been break up the banks and it didn't seem, in reading his answers, that he understood exactly how that would work under Dodd-Frank and exactly who would be responsible, what the criteria were.' 

'And that means you can't really help people if you don't know how to do what you are campaigning on saying you want to do,' Clinton added.  

 Asked again if Sanders was ready to be president of the United States, Clinton again punted from delivering a definitive answer.

'Well, I think he hadn't done his homework and he's been talking for more than a year about doing things that he obviously hadn't really studied or understood and that does raise a lot of questions,' she said. 

Clinton said that voters need to examine whether Sanders can 'deliver' on many of his oft-repeated campaign promises. 

'Obviously I think I'm, by far, the better choice,' she added. 

Scarborough again asked the former secretary of state if she thought Sanders 'qualified' to be president and whether she thought he would deliver on those promises. 

Hillary Clinton campaign in Philadelphia today and also sat down with the hosts of Morning Joe and Chris Cuomo of CNN to try out some new lines against rival Bernie Sanders 

Hillary Clinton laughed and called it 'ludicrous' to suggest that she was destroying the Democratic party with her presidential ambitions, something Bernie Sanders' campaign manager asserted last night 

'Well, let me put it this way Joe, I think what he has been saying about the core issue in his whole campaign doesn't seem to be rooted in an understanding of either the law or the practical ways you get something done,' she answered. 

On CNN several hours later, it was the word 'surprised' that Clinton used to describe her reaction to Sanders' New York Daily News interview. 

'I was a little bit surprised that there didn't seem to be a lot of substance to what he was saying,' she told the network's Chris Cuomo. 

When Cuomo challenged Clinton, suggesting perhaps the specifics didn't matter, she hit right back.  

'Well, that's not the way I've seen it work,' she said, explaining that a president should be able to 'hit the ground running' in regards to the dual job as president and commander in chief. 

She also laughed loudly at comments Sanders' campaign manager Jeff Weaver uttered the night before. 

'Don't destroy the Democratic Party to satisfy the secretary's ambitions to become president of the United State,' Weaver had warned during a Tuesday appearance on CNN. 

Clinton let out her trademark cackle. 

'It's just ludicrous on the face of it,' she said. 'You know, I have been campaigning for Democrats, fundraising for Democrats, recruiting Democrats to run and win and for a really long time, I think for forty years, and Sen. Sanders by his own admission hasn't even been a Democrat.' 

'So look, I understand they are getting anxious, I get that, but they need to be thoughtful about what they do say because at the end of the day we need a Democratic president to succeed President Obama and to protect further the progress we've made under his eight years in office,' Clinton said.
