Should I consider this matter seriously, I would vote for Hillary Clinton. True, Obama does have the style. However as of right now, U.S. is in serious deep shit. Political division; the Iraq war which can never be won for obvious reasons; lack of public fund to support public services such as school or health care; the retirement of baby boomers; the fall of the big three; illegal immigration issue, problematic economy; so called war on terror; petroleum problem - just to name a few.
Obama may not be losing to Hillary in an IQ test, but face it, I don't think he's capable of dealing the huge mess U.S. is currently in. He has less control on the senate, less respect, less experience and less overall abilities to deal with the issues that I have listed above. Hillary on the other hand, is an experienced veteran. Personally, I have great respect for her husband and hope he would aid Hillary in the future.
Right now America doesn't need a new direction that leads to who knows where, it needs a powerful leader. Obama doesn't make the cut.
