Sen. Mark Begich, D-Alaska, raised just under $1 million in the first quarter of the year, according to a copy of his fundraising report obtained by CQ Roll Call.

Begich raised $948,000 from January through March and had more than $1.5 million in cash on hand at the end of last month.

That’s a solid start for the targeted incumbent Democrat, especially considering the Frontier State’s relatively inexpensive media markets. (See more fundraising totals in Roll Call.)

The Begich campaign noted in a press release that it has received contributions from more than 1,000 new donors since the 2008 election, when Begich defeated incumbent Republican Ted Stevens.

Begich still doesn’t officially have an opponent, but Lt. Gov. Mead Treadwell is taking a serious look at the race. Joe Miller, who ran for Senate in 2010, is also considering a bid.
