I guess the question to ask is who will win the election if voters decide based on which candidate they expect to do better in handling the issues? I came across a new research study that addresses this question.
The result: historically, voters chose the candidate they expected to do the best job in dealing with the issues facing the country. For 2008, the approach predicts Barack Obama as the election winner.

Bush is one of the least articulate, curious US presidents of all time. It's dangerous to have an unintelligent man as the commander in chief, and the executive in chief of a country. I don't want Palin to be a heart beat away from the president. She sounds like another Bush. She couldn't articulate why being in close proximity to Russia has any to do with being capable to deal with relation with Russia. She doesn't have the knowledge of global events, she couldn't come across as in command when doing a sit down interview, she blamed the press for the unexpected "got'cha " questions, she has only done 4 interviews and they have all been diasterious. That is enough to prove that McCain has very bad judgement in picking the most capable person to help him run the country. He has put party politics before the country.
