Delaware House candidate John Carney blasted his own party for delaying a vote on the extension of expiring tax cuts until after Election Day.
"I'm disappointed that leaders in Washington decided to delay a critical vote on extending tax cuts," the former lieutenant governor said in a statement.
Senior Senate Democrats told The Hill they plan to leave Washington by the end of next week without voting on an extension of the George W. Bush-era tax rates, which are set to expire at the end of the year.
"Even though people across Delaware and our country continue to struggle during these tough economic times, politicians in Congress keep choosing partisan politics and gridlock over helping middle-class families," Carney said.
Some liberals have also expressed outrage that Democrats are not holding a vote to extend tax cuts for the middle class before the elections.
Carney faces Republican Glen Urquhart in the race for the seat being vacated by Rep. Mike Castle (R-Del.).
