The Hill has the story. Kerry could be had -- either in a primary, or the general. But it would definitely take a strong challenger -- think sitting Congressman, or former Governor. None of those is in the offing -- at least not yet.
In fact, some analysts see Kerry among the more vulnerable incumbents up for reelection in 2008. Whether that translates to his defeat in 2008, however, is a far different question.
In a state as blue as Massachusetts, the Democratic Party is lined up firmly behind the fourth-term senator. Combine that with the $11 million already in Kerry’s campaign fund, and the task for any challenger is tall.
“The polling that’s out there shows that if he decided not to run, voters would be OK with that,” said Jennifer Duffy of the Cook Political Report. “And he may be vulnerable to a primary challenge, but it’s going to have to be a really serious one.”
According to the Boston Globe, the filing deadline in Massachusetts is not until May, 2008 -- so a former presidential candidate could still challenge Kerry -- if he chose to do so.
Just some idle speculation...
