Sen. Blanche Lincoln (D-Ark.) is sending out a flurry of e-mails to supporters ahead of Tuesday’s primary runoff against Lt. Gov. Bill Halter (D).

On Wednesday she sent a fundraising plea from Vice President Joe Biden, who noted how she stood with the administration on key priorities.

“Blanche has a consistent record of fighting for Arkansas,” Biden wrote. “That record includes standing with me and President Obama to pass the most historic health reform this country has ever seen.”

And on Thursday her campaign sent a note to supporters highlighting how she’s willing to “work across the aisle to get things done.”

Lincoln’s husband, Steven, wrote: “Blanche is a rare breed. She's one of the few senators left who are willing to work across the aisle to get things done.”

Lincoln has also brought former President Bill Clinton in to campaign for her in what is a tough election year for incumbents. She's already seen colleagues Sens. Bob Bennett (R-Utah) and Arlen Specter (D-Pa.) lose their primary bids.
