Little Rock, Arkansas (CNN) - Log on to Blanche Lincoln's campaign website and you will see a detailed, county-by-county list of money and programs the two-term Democratic senator has secured for Arkansas.
Usually that "look-what-I've-done-for-you-lately" pitch can help embattled incumbents assuage voters' concerns. But this election year is anything but usual.
Lincoln is trying to avoid becoming the third sitting Democratic lawmaker this year to be defeated by a fellow Democrat in a primary battle, but Democratic sources in Washington and Arkansas tell CNN they're not sure she can pull off a win Tuesday.
Her challenger, Lt. Gov. Bill Halter, forced moderate Lincoln into a runoff not by coming at her from the left, but from the outside - with a classic 2010 anti-Washington message.

"Arkansans around the state are telling me that they want a change, and they know that if you send the same people to Washington, you're guaranteed to get the same results," Halter said during a weekend campaign stop.
