Is Newt Gingrich Fit to be President?

Newt Gingrich is running for President, but is he ready to be president?  His ex-wife doesn't think so.  In an interview with ABC News, she said that the former Speaker came to her asking for what she called an open marriage.

Texas Governor Rick Perry came out with an endorsement of Gingrich today, but I can imagine that his comments about cheating on your wife will not help Gingrich much in the coming days.

Does this matter to you in the grand scheme of the election?  Is he fit to be Commander-in-Chief?
