I know Mark Pryor personally, and he is a wonderful Senator. Arkansas is a much more Democratic state than people give it credit for, and Pryor is very popular. His dad served in the Senate for 24 years, and was also the governor. If Hillary wins Arkansas (which I think she will), then Pryor should coast to reelection.
Yes, Arkansas is a very democratic state; however, I've found something that, initially, took me rather by surprise
Assuming all states allocated their Electoral votes in the same way as Maine and Nebraska, Arkansas would have been the only 'Dixie' state not to have cast a single vote for Kerry. Then it occurred to me, that she has no African-American majority congressional districts
Pryor should be re-elected easily enough in 2008
