The latest addition to our round-up of Senate polls has some politically earthshaking news, with Alaska Sen. Ted Stevens looking increasingly vulnerable against his Democratic challenger, Anchorage Mayor Mark Begich.

–
**Alaska:** As he begins to generate name recognition throughout the state, Begich is leading Stevens 51 percent to 44 percent, with a margin of error of 5 points, according to a Hellenthall and Associates survey conducted May 6-10 and reported today in the Fairbanks Newsminer. A Rasmussen Reports survey conducted May 14 had shown Stevens trailing Democrat Begich by 2 points, with the Anchorage mayor leading the 6-term senator 47 percent to 45 percent. The margin of error in that poll was 4.5 percent. Begich was viewed favorably by 58 percent in the Dittman poll compared to 16 percent who had a negative opinion. Elevn percent did not know him. Stevens’ favorability rating was 49 percent against 40 percent, and all respondents knew the six term incumbent. Although we’re talking Senate here, Alaska’s other longtime incumbent, 17-term Rep. Don Young, would run way behind Alaska House Minority Leader Ethan Berkowitz if Berkowitz gets his party’s nomination. Berkowitz leads 58 percent to 38 percent.
