"If Jeb Bush has a sincere shot in 2016, why didn't he run in 2012?"
Because incumbent presidents usually get reelected.
During the 100 year period between 1912 and 2012, only four incumbent presidents failed to win re-election.
Quick question.........................why is it that Bush Sr. failed to win re-election?
I mean.............he lost to Clinton who was a definite liberal.
The Bush family are weak. H.W. is a 1-term president, no one claims W. as a conservative, and his presidency is extremely unpopular.
Romney lost a general election to an incumbent at a time where the GOP held no public favor on any major issue. Doesn't look too awful compared to the Bush family
