Both Massachusetts senators, John Kerry and Ted Kennedy, have close experience with presidential campaigns, so who can blame them for waiting a little bit to make an endorsement? Kerry's dominance in the last go-round came as a surprise after the Dean campaign collapsed in Iowa. The field of Democrats is deep this year, and, like Deval Patrick, our Senators have to be cautious about making endorsements since the Clintons are such a powerful force.

But at least one Senator, John Kerry, has made a move and is backing Obama. It's surprising that Kerry made an endorsement before Kennedy since he is famous (or maybe infamous) for his caution and deliberation in most matters.

Somewhere out there, John Edwards, Kerry's former running mate, is feeling the sting. But he's in a solid third place, so Kerry may have felt he'd be throwing away his endorsement.

Now Democrats are wondering who Kennedy will choose to endorse. This will likely give rise to whether or not the Kennedys still matter, but the Kennedy Stamp of Approval might sway a voter or two.
