The more I think about an Obama-McCain race, the more I think that it will be a landslide: for McCain.
The Obama balloon will burst. There is no substance there, at all. Obama may be the most unqualified person to ever seriously run for President. When voters start comparing the two candidates, the difference in substance and experience will be evident.
While their is a clear difference in age and vitality when the two candidates are seen together, I think that it will ultimately work against Obama. We aren't chosing up sides for the office softball game. I think that the voters will realize that as the initial enthusiasm for Obama begins to wane.
While conservatives are alarmed by McCain's actions, these same actions play well with independents and moderate Democrats. The more Obama is seen and exposed, the more these people will see McCain as a viable option in the general election.
By the general election, all but the most rock-ribbed of conservatives will be on board with McCain. So his base will be secure, even if not enthused.
You think too highly of democrat voters and other leftists. Have you seen the crowds squealing when Obama speaks? I doubt there's a dry seat in the house by the time he finishes.
