President Obama is following through on a promise to help a potentially vulnerable member of the Senate Democratic caucus, with a trip planned later this month to Connecticut to raise money for Chris Dodd.

"Obviously we're extremely grateful that President Obama has taken time out of his busy schedule to campaign on behalf of Senator Dodd, and we're looking forward to a great event," campaign manager Jay Howser said in a statement from Dodd's campaign today.

Dodd has been a frequent guest at White House events this year, often getting high presidential praise at policy announcements and bill signings. In an interview this April, Obama told the Boston Globe: "I can't say it any clearer: I will be helping Chris Dodd because he deserves the help."

In addition to the October 23 fundraiser with Obama, Vice President Biden will travel to Fairfield, Ct., this Monday for an official event with Dodd to promote a project made possible through the Recovery Act.

The field of Republicans challenging Dodd has grown larger by the month, with WWE CEO Linda McMahon the most recent entrant. A recent Daily Kos/Research 2000 poll showed Dodd leading three of four potential rivals, trailing only former Rep. Rob Simmons (R).
