Even as Senate GOP Conference Vice Chairwoman Lisa Murkowski considers running as a write-in candidate in the November general election, the Alaska Republican’s colleagues on the GOP leadership team have cut her loose and begun to line up behind Joe Miller.

Senate Minority Leader Mitch McConnell (R-Ky.) has contributed $5,000 to Miller’s campaign through his Bluegrass political action committee. Additionally, an official with the National Republican Senatorial Committee confirmed Wednesday that a $42,600 donation to the Fairbanks attorney was in transit to his Alaska campaign headquarters. This official also said the NRSC has pledged to spend roughly $170,000 in coordinated funds.

All dollar amounts constitute the maximum allowed under the law.

Murkowski conceded defeat to Miller in the Alaska Republican Senate primary last week. Sources say she could announce a write-in candidacy as early as Thursday. Sitka Mayor Scott McAdams is running for the Democrats.
