You should have some faith in your man, Winfield.
So you're admitting that Mitt will win in 2012, and saying that I doubt he will win re-election in 2016.
Romney will be young enough to try again in 2016 if he loses this time and then run for reelection in 2020 if he wins in 2016.
Romney will be 69 in 2016, younger than Reagan was while elected to is first term as well as younger than McCain in 2008. Not to mention Bob Dole, lol.
Yet if Romney loses in 2012, I have really hard time seeing him having a shot again in 2016. Remember that a lot of strong potential candidates decided to sit out this season.
