The Politico is reporting that Barack Obama will travel to the Bay State on Sunday to campaign for beleaguered Democratic Senate candidate Martha Coakley.

Given Obama’s non-impact (some might say negative impact for Democrats) in New Jersey, it is far from clear whether his appearance in Massachusetts would help or hurt Coakley, especially since even in that bluest of blue states a new poll indicates that the current health care reform proposals, Obama’s political signature at this moment, have more opposition than support.

Add in Barney Frank’s statement that a Brown win in Massachusetts could spell the death of health care “reform", a visit by Obama could actually increase turnout for Brown among independent voters who are by large majority against Obamacare.  While many people correctly point out that Democrats outnumber Republicans in Massachusetts by about 3-to-1, too many forget to note that the state’s independent (called “unenrolled” in MA) voters outnumber Democrats and Republicans combined.

In the meantime, political betting now has Martha Coakley still in the lead, but just barely, trading around 60% as I write this, down from over 90% just a week ago.

I’m not counting any chickens.  This is, after all, an election in Massachusetts to replace Ted Kennedy.  But were Brown to win, it could change everything about the current dynamic in Washington, D.C.
