Meghan mccain gingrich, As questions about Newt Gingrich's past infidelity have hit him in the polls, one GOP mouthpiece warns his current wife may cost him the presidency.

Meghan McCain, the daughter of Sen John McCain, a blogger and MSNBC correspondent, targeted Callista Gingrich in a bizarre attack today.
Callista is Mr Gingrich’s third wife, and it has been revealed that she and Gingrich had begun a relationship while the ex-House speaker was still married to his second wife, Marianne.
Miss McCain said she believes that a background like that could sink Mr Gingrich's hopes of being in the White House.
'I think the fact that she was a third wife and a mistress and is coming off somewhat icy and [her] reputation of being somewhat controversial within their campaign is doing damage.'
She added: 'Maybe just to politicos, but I think it's something that people, and especially values voters, will bring into the race.'
But Miss McCain’s father John McCain, twice a presidential candidate, is on his second marriage to Cindy McCain, Meghan's mother.
The couple began dating in 1979, but Mr McCain’s first marriage did not officially end until 1980, according to a 2008 L.A. Times report.
Miss McCain joined MSNBC as a contributor last month about the same time as another political daughter, Chelsea Clinton, got a similar NBC gig.
