This is the second quarter in a row that Begich has raised nearly $1 million. He now has more than $2 million in the bank, money that will go far in inexpensive Alaska.

Begich is the latest Senate Democrat to post strong fundraising numbers heading into a year where Democrats are playing defense and trying to hold control of the chamber. His seat is likely one of three or four that will determine which party controls the Senate.

It remains uncertain who Begich's opponent will be. Alaska Lt. Gov. Mead Treadwell (R) is the front-runner at this point against 2010 Senate nominee Joe Miller (R). Former Alaska Gov. Sarah Palin (R) has been making noises about a run, but few expect her to take the plunge.
