Former Colorado Senate candidate Andrew Romanoff (D) is holding a birthday party to help retire his campaign debt.

Romanoff, who lost to Sen. Michael Bennet (D-Colo.) in the Aug. 10 primary, tweeted Thursday: "A friend said she hoped that someday I'd have a birthday party without a cover charge. This is not that day."

His office is asking supporters to give $44, $144 or $1,044 in honor of his 44th birthday earlier this week. Thursday's party will be at his campaign headquarters.

During the race, Romanoff sold his home to infuse his campaign with some last-minute cash. He was reported to be $350,000 in debt after the primary.
