As much as I think Dubya was a poor president, I can see where some would think he'd be better than anyone currently striving for the Republican nomination. He's certainly better than any of the frontrunners right now.
Indeed.
And honestly, this is why Republicans will probably lose 2016. They haven't gotten over the Bush years and Bush mentality. Mind you, neither have the Democrats, but they don't have Bush's legacy to deal with...
From a policy perspective, the worst thing George W. Bush did for America was to essentially remove a "boots on the ground" military option from the table for an entire generation.
Well, that and the worst recession since the 1930s.
Presidents have very little control over the economy.
