LOS ANGELES (AP) — A smackdown among presidential candidates?

Barack Obama, Hillary Rodham Clinton and John McCain will appear on World Wrestling Entertainment's live "Monday Night Raw" (8-11 p.m. EST on cable's USA network) but instead of smacking each other down, they separately will deliver some wrestling-themed stumping in taped messages before Tuesday's Pennsylvania primary.

"Tonight, in honor of the WWE, you can call me Hillrod," Clinton says in her message. "This election is starting to feel a lot like 'King of the Ring.' The only difference? The last man standing may just be a woman."

Obama borrows The Rock's famous catchphrase during his appearance.

"To the special interests who've been setting the agenda in Washington for too long and to all the forces of division and distraction that has stopped us from making progress, for the American people, I've got one question: Do you smell what Barack is cooking?" Obama says before flashing a smile.

McCain, meanwhile, looked to Hulkamania for inspiration for his message.

"Looks like Hillary Clinton and Barack Obama want to celebrate their differences in the ring," McCain says. "Well, that's fine with me, but let me tell you: If you want to be the man, you have to beat the man. Come November, it'll be game over. And whatcha gonna do when John McCain and all his McCainiacs run wild on you?"

The candidate appearances will be used to promote "Smackdown Your Vote!" — the WWE's voter registration drive.
