Ross Perot will vote for Mitt Romney and slams McCain in this Newsweek interview:

Perot says he intends to vote for Mitt Romney in the Texas Republican primary on March 4, citing Romney's experience in business and his family values. "When I went to the Naval Academy and met my first Mormons I asked why so many were excellent officers," Perot recalls. "I learned it was because of their strong family unit."...

The Perot-McCain relationship goes back to McCain's five and a half years of captivity in Hanoi. When McCain's then-wife Carol was in a serious car accident, McCain's mother called Perot for help. "She asked me to send my people to Philadelphia to take care of the family," Perot says. Afterwards, McCain was grateful. "We loved him [Perot] for it," McCain told me in 2000.

Perot doesn't remember it that way. "After he came home, he walked with a limp, she [Carol McCain] walked with a limp. So he threw her over for a poster girl with big money from Arizona [Cindy McCain, his current wife] and the rest is history."
