Lt. Gov. Bill Halter (D) is continuing to pull in significant amounts of campaign cash from national progressive groups. He sent an e-mail to supporters of the Progressive Change Campaign Committee on Monday to thank them for helping him raise $250,000 ahead of Tuesday's vote.

"Thousands of PCCC members gave $250,000 in small-dollar donations, which went to fund our grassroots field operation and TV ads," Halter wrote in the e-mail. "You also helped make over 200,000 phone calls to voters in the final days, allowing us take the lead in the polls."

Halter is up against Sen. Blanche Lincoln (D-Ark.) in the runoff for the Democratic Senate nod.

A spokesman for PCCC said the group "has had senior staffers on the ground for the past couple months, leading Halter's field operation."
