Who do you think should be the next big political figure to go vegan?

• Barack Obama. We could see Michelle jumping on board and creating all kinds of healthy vegan meals from the White House garden.

• Dick Cheney. Considering his tricky ticker, he should take up tofu.

• Al Gore. If he truly wants to be Al Green, he's gotta go vegan.

• Sarah Palin. Vegetables are so good for you eyesight, she’d be able to see Russia even on a cloudy day.
