Senator Ted Kennedy will be endorsing Barack Obama for President on Monday, following his niece Caroline’s endorsement of Obama today in the New York Times. The endorsement from this unreconstructed liberal, and a titan to the party’s left-wing base, should help Obama with the lower-income and less-educated voters he has been losing to Hillary in every contest. No longer, Obama’s supporters will claim, is he the candidate of just college candidates and Cantabridgians.

It will be interesting, however, to see how these same people square away their candidate’s persistent promise of “change” and unmooring American politics from the smoky, back room dealings of the past with an endorsement from the standard-bearer of one the country’s oldest and most notorious political dynasties.
