GOP Senators Isakson, Bennett Back START

Two more Republicans have come out in favor of the START nuclear weapons reduction treaty with Russia, with the agreement appearing to be on track for the constitutional requirement of a two-third majority for ratification.

Sens. Bob Bennett (R-UT) and Johnny Isakson (R-GA) have announced their support, following an earlier announcement this morning by Sen. Lamar Alexander (R-TN). In addition, Sen. Bob Corker (R-TN) is expected to announce his support later today — which would officially put it over the magic number.

Republican Senators who had already announced their support are Richard Lugar (IN), Susan Collins (ME), Olympia Snowe (ME), Scott Brown (ME) and George Voinovich (OH).

Bennett was defeated for renomination at his Republican state convention earlier this year, due to a Tea Party-backed challenge, while Isakson was just re-elected this past November.
