Mark Begich—Alaska

Mark Begich is the current mayor of Anchorage and the Democratic Party's top pick to run against noted Internet tubologist Ted Stevens. Even before Begich officially announced he was throwing his hat in the ring, he was already polling a half-dozen points ahead of Alaska's scandal-plagued senior Senator just on spec. Stevens' approval rating is seriously negative even in his rather right-leaning home state, so Begich has a good chance of de-throning old Ted in November -- if, that is, old Ted is who he ends up running against. If his problems with the IRS and the FBI outrun his evasive tactics, Stevens may have to cede the field to another Republican candidate instead.
