His biggest weakness should have been Obamacare, but the selection of Romney nullifies that.
Obama’s biggest weakness is not the economy. It’s the disenchantment of so many whites who bought his 2008 message of of a new post racial tranquility, only to discover that he is a race baiting opportunist in the vein of Al Sharpton.
0bama’s scorched earth campaign may energize his base, but it will alienate everyone else. Democrats used to be better at this kind of stuff. This election, however, they are taking on a more bitter tone, and that will help Romney more than 0bama.
