AUGUSTA, Maine (AP) Republican U.S. Representative Bruce Poliquin of Maine reports more than $2.2 million in his campaign war chest as Democratic opponents make their case to donors ahead of the June 12 primary.

Democrats, including Assistant Maine House Leader Jared Golden; conservationist Lucas St. Clair; farmer and carpenter Jonathan Fulford; and bookseller Craig Olson recently filed campaign finance reports as they compete to face the congressman in November.

National Democratic groups have announced plans to try to flip Maine’s House seat. Meanwhile, a Republican political action committee is opening an office in Maine to support Poliquin’s re-election bid.

Among Democrats, Golden reports about $300,000 on hand. He’s raised the second-highest amount of funds so far.

Poliquin campaign strategist Brent Littlefield notes Poliquin has $400,000 more in the bank than this time two years ago.
