Washington (CNN) - Vice President Joe Biden travels to Boston Wednesday, where he's scheduled to team up with Sen. Blanche Lincoln of Arkansas.
A Democratic source tells CNN that the event is a fundraiser for the two-term Democratic senator, who faces a very difficult re-election bid this year.
After surviving a very tough primary challenge from Arkansas Lt. Gov. Bill Halter that extended to a run-off election, Lincoln now faces off against four-term Rep. John Boozman, the Republican Senate nominee.
A recent Mason-Dixon poll of likely Arkansas voters indicated that Lincoln trailed Boozman by 17 points. Other recent surveys suggest that Boozman's lead is even larger.
