Rep. Barney Frank endorses Rep. Ed Markey for MA Senate seat

While Barney Frank has clearly stated he'd like to be the interim Senator from Massachusetts (should John Kerry become Sec. of State), he's now endorsed MA Rep. Ed Markey for the special election that would take place:

Markey was the first candidate to announce that he is running in the special election. Frank’s endorsement comes days after Kerry, Victoria Kennedy, the Democratic Senatorial Campaign Committee and other Democratic groups announced that they are backing Markey, in an apparent attempt to coalesce around one Democratic nominee and avoid a contentious primary. However, not all Democrats are ready to unite around Markey. U.S. Reps. Michael Capuano of Somerville and Stephen Lynch of South Boston and state Sen. Benjamin Downing of Pittsfield are all still considering running.
