Ted Kennedy to endorse Obama today

Ted Kennedy will follow in the footsteps of his niece Caroline and endorse Barack Obama's presidential candidacy today, according to published reports:

Both the Clintons and their allies had pressed Mr. Kennedy for weeks to remain neutral in the Democratic race, but Mr. Kennedy had become increasingly disenchanted with the tone of the Clinton campaign, aides said. He and former President Bill Clinton had a heated telephone exchange earlier this month over what Mr. Kennedy considered misleading statements by Mr. Clinton about Mr. Obama, as well as his injection of race into the campaign.

Mr. Kennedy called Mr. Clinton Sunday to tell him of his decision.

The endorsement, which followed a public appeal on Mr. Obama’s behalf by Caroline Kennedy, the daughter of President John F. Kennedy, was a blow to the Clinton campaign and pits leading members of the nation’s most prominent Democratic families against one another.

Mr. Kennedy, a major figure in party politics for more than 40 years, intends to campaign aggressively for Mr. Obama, beginning with an appearance and rally with him in Washington on Monday.
