Behind the jokes on national television about back waxing, Gov. Charlie Crist is in a fight for his political life.

A poll released Tuesday shows former House Speaker Marco Rubio trouncing Crist for the Republican Senate nomination, 60-28.

The landslide margin reported by Public Policy Polling (PPP) of North Carolina is being read as another sign of deterioration -- if not impending implosion -- by a campaign that had held a similarly commanding lead just three months ago.

The PPP polling was done March 5-8, well after the dust-up over Rubio's questionable GOP credit card expenditures.

Still, on the eve of Tuesday's poll release, Crist was on Greta Van Susteren's Fox News show, making snarky suggestions about Rubio getting a back wax along with his $135 haircut.

Was it an attempt at humor or an act of desperation?

Either way, Florida Republicans are jumping off the Crist bandwagon in ever-increasing numbers. The once popular governor hasn't won a county straw poll in months, and the PPP numbers show Rubio up a whopping 71-17 among self-described "conservatives."

If there was one silver lining for Crist, it comes from GOP moderates. He holds a seven-point lead in this group, but they account for less than one-third of likely primary voters.

So where does Crist go for votes? Try independents.

According to an earlier survey by Research 2000 for the Daily Kos blog, Crist enjoys a 58 percent favorable rating among voters registered as independents or unaffiliated. He took 33 percent of that vote to 32 percent for U.S. Rep. Kendrick Meek, the leading Democratic contender, and 27 percent for Rubio.

Crist has repeatedly denied entertaining an independent bid -- and he did so again on Tuesday morning before the PPP poll was released.

In a radio interview with the Washington Times, Crist said, "What I'm doing is running as a Republican. I'm proud of my party, proud to be from the party of Abraham Lincoln, Ronald Reagan, Teddy Roosevelt."

Then again, Connecticut Sen. Joe Lieberman and Pennsylvania Sen. Arlen Specter pooh-poohed the independent strategy before ultimately leaving their party.

If Crist changes his mind and goes independent, he'll have to declare his intentions soon. The filing period ends April 30.

In a statement released with the poll, PPP stated, "Our general election Senate numbers, which we’ll release (Wednesday), find that Crist is a good deal more popular with Democrats now than he is with Republicans. His path to any future electoral victory may come as an independent or perhaps even as a Democrat."

Responding to Tuesday's poll, Crist campaign spokeswoman Amanda Henneberg called the survey "clearly agenda driven."

"The firm conducting the poll is a well-known Democrat firm who uses the unreliable method of push-button polling. It is a Democrat poll designed to help Speaker Rubio, as they understand how easy it would be to defeat a lobbyist-politician in November.

"Looking at the questionnaire, it is obvious the types of questions asked and the order in which they were asked pre-determined the outcome. The questions cited were asked after intentionally questioning the governor's party loyalty as well as ideology, the same was not done for Rubio."

Andrea Saul, communications director for the Crist campaign, added:

"Polls like this reflect the mood of the electorate, and the electorate is in a bad mood. Ultimately, elections are about choices: This election will come down to the choice between an honest public servant with a strong conservative record in Charlie Crist and a Miami lobbyist-politician Marco Rubio, who has traded on his connections for everything from $135 haircuts to fat lobbying deals.

"Charlie Crist will win this race and win it decisively."

If Crist stands and fights for the Republican nomination, political analysts expect him to come out with guns blazing. And, he has the financial arsenal to do it.
