As yet another make-or-break day on the campaign trail approached for Hillary Clinton, the New York senator could take comfort in the fact that she was going to a place where everybody would know her name.  

She had Ted Danson right beside her, after all. 

The former Cheers star and wife Mary Steenburgen hitched a ride with Clinton as the presidential candidate took off from Cleveland, Ohio, on Sunday after a day spent in the Buckeye State rallying supporters in advance of Tuesday's Democratic primary. 

But while Clinton, has an Emmy and an Oscar winner firmly in her corner—and on her chartered plane!—she has seemingly lost all of her momentum in the face of Barack Obama's surge in popularity since Super Tuesday, when the former First Lady logged big wins in California and New York. 

On Tuesday, there are what pundits are calling do-or-die primaries in Texas and Ohio, meaning Clinton practically has to win both to retain any hope of capturing the Democratic nomination. 

And although she already took California, it wasn't due to La-La Land's lack of support for Obama. 

When asked how he felt about longtime pal and Curb Your Enthusiasm costar Larry David backing Obama, Danson told a reporter for the Tribune Co.'s Washington bureau: "I’m out of that show. I’m never going to do it." 

The reliably acerbic David joins a growing legion of celebs male and female, black and white, young (one of Obama's biggest bastions of support) and old. 

In addition to big-time Obamians such as George Clooney, Oprah Winfrey and Matt Damon, celebs who have gotten behind the charismatic senator from Illinois include Sharon Stone, Halle Berry, Ben Affleck, Jessica Alba, Scarlett Johansson, Stevie Wonder, Dave Matthews, Alfre Woodard, Mariah Carey, Harold Perrineau, Hill Harper, Jonathan Schaech, Enrique Murciano, Eric Balfour, John Legend and Kareem Abdul Jabar, (many of whom showed up in Will.i.am's "Yes We Can" videos).

Meanwhile, Jack Nicholson, with help from director pal Rob Reiner, put together a video endorsing Clinton via snippets of dialogue culled from a number of his iconic roles, including his delusional dad in The Shining, the Joker from Batman and his adrift ex-piano prodigy in Five Easy Pieces. 

Other Clinton stalwarts have included Steven Spielberg (who, in the spirit of Democracy, also cohosted an Obama fundraiser with DreamWorks partners Jeffrey Katzenberg and David Geffen last year), Barbra Streisand, Glenn Close, Danny DeVito, Magic Johnson, Roseanne Barr and Quincy Jones. 

Forest Whitaker, Samuel L. Jackson, Kerry Washington, former O.C. star Ben McKenzie and Kate Walsh have all campaigned for Obama around Texas in recent days, while America Ferrera and Sean Astin stumped for Clinton in Austin. 

Eva Longoria Parker and Melanie Griffith were scheduled to appear at a town hall meeting with Clinton on Monday.   

(On the other side of the coin, Tom Selleck, Rip Torn and California Governor Arnold Schwarzenegger, among others, have come out in favor of Republican frontrunner John McCain, who barring a freak occurrence will almost certainly be the one squaring off against Clinton or Obama come November.)
