National elections are different animals though. It is one thing to vote against Congress and quite another to kick someone out of the WH. Face it, there are 40 plus % of the population that will vote D or R every time they vote.
On the whole, Palin might be popular with the automatic R voters but the 18-20% that are not loyal to the R party have concerns about her. I don’t think they can justify voting for BO though.
Will be interesting to watch
I think Obama has scared too many for this to be accurate. Wonder what the internals were.
Presidential incumbents ALWAYS have an advantage. Since 1936, only two challengers have unseated incumbent Presidents who were standing for reelection - Ronald Reagan and Bill Clinton.
Interestingly, both times there was a Independent candidate that did reasonably well; Ross Perot in 1992 who managed almost 20% of the popular vote and John Anderson in 1980 who garnered 6% of the popular vote. In each instance, those "successful" independent candidates were probably more reflective of the country's anger at the incumbent's party and their nominee.
