Will Caroline run for Uncle Teddy's seat?

I just read that Caroline Kennedy is going to be one of the speakers at the AFL-CIO convention in Pittsburgh. Is this the first step in a run for her Uncle Teddy (and before him, her father's) Senate seat? You may say "Yeah, but Caroline lives in New York!" Well, Hillary Clinton was a resident of Arkansas when she began her 'listening tour' to become New York's junior senator and Caroline at least has family ties to Massachusetts. If Vicki or Joe Kennedy decide not to run, look at Caroline to.
