Sen. Blanche Lincoln (D-Ark.) wasn't outraised in the first quarter by as much as previously thought, but she did spend heavily.

Lincoln's campaign just came out with some more specific numbers. It turns out she raised more than $1.3 million (versus the "more than $1 million" previously reported) and has $4.3 million on hand. Lincoln's cash on hand dropped by about $700,000, meaning she spent heavily -- about $2 million -- defending herself in the primary.

Lt. Gov. Bill Halter (D), who is challenging Lincoln in a primary, raised $2 million in the first quarter. He raised that amount in a shorter time period, though, having entered the race late in the quarter.

Republican frontrunners Rep. John Boozman (R-Ark.) and state Sen. Gilbert Baker have yet to announce their first quarter totals.
