As far as bench strength on the Republican side, I don't see much out there. This is where the party needs to concentrate on governor races, because that's where Presidents should come from. The Democrats have let the Senators hijack the nomination process, and as a result the three top Democrats have ZERO practical experience to brag about. The media would like to forget that, but the voters won't.
One thing for sure; if a Democrat is elected in 2008, hopefully we won't repeat the Bob Dole mistake of 1996. It's time to start over, and everybody in the top 5 this time around should be not considered next time.
One thing that is certain though it will not be the last time a Kennedy appears in the election cycle in one form or another and this dynasty has been around far longer.
