New details this morning as Caroline Kennedy starts her bid to claim Hillary Clinton’s vacated Senate seat. According to The New York Times, Kennedy has called several prominent New York machers and plans an upstate trip similar to Clinton’s famous “listening tour” to firm up support. Sources close to Gov. David Paterson, who will make the appointment, say that Kennedy is now a “clear front-runner.” “The upside of her candidacy is that the 2010 ballot will read Kennedy-Paterson,” a source told the paper. “David craves national attention and money. If you connect the dots, it leads to her.” A source tells the Daily News, “She is in.” The New York Post reports that Kennedy has the quiet support of New York City Mayor Michael Bloomberg.
