Sen. John Kerry (D-MA) "may have competition for the Democratic Senate nomination in 2008," reports the Gloucester Times. Defense attorney Edward O'Reilly "said yesterday he will formally announce his bid at this weekend's Democratic Party convention in Amherst."
"The former Gloucester city councilor and School Committee chairman said Kerry's vote to authorize force in Iraq in 2002 is one reason why he's running."

So he's going to campaign on that Kerry originally voted for the Iraq war, no matter how much he opposes it today? I see no reason why this would work- it's nothing like Connecticut, where Lieberman lost the primary because he was actually pro-war.
If the Republicans were to put forward a credible candidate, it would have to be someone outside of state politics, as none of the Rep. state senators/representatives have any name recognition outside their own district. And Mitt Romney has talked insulted Massachusetts enough that he will not be a help to anyone lower down the ticket and certainly could not run on his own here.
