Jeb Bush was born in 1953. My guess is that, if does eventually run, he would do so for the year 2016.
This.
And it makes so much sense to, too. He stands no chance in 2012 because the Bush name is tarnished. Come 2016, people will have grown up and realized that just because his brother was deemed bad doesn't mean he will follow suit. Run in 2012 and be smeared as he would be would end his chances for good.
That's why I'm glad Romney didn't get the nomination in 2008. He has a chance now in 2012, which I think he wouldn't have had if he faced a devastating loss in 2008.
