PORTLAND — Two Democrats hoping to unseat Republican Sen. Olympia Snowe of Maine are critical of her for failing to support President Barack Obama’s choice to lead a financial watchdog office.

Senate Republicans have stopped a former Ohio attorney general, Richard Cordray, from becoming director of the Consumer Financial Protection Bureau. A vote to overcome a GOP filibuster failed Thursday.

Snowe voted “present.” Snowe recused herself from the vote because her husband is involved in student loans, something the agency will help to oversee.

Two Democrats vying for their party’s nomination attacked Snowe for failing to stop the filibuster. Matt Dunlap said Snowe is helping to kill an agency she helped to create. Jon Hinck accused Snowe of siding with the interests of Wall Street bankers and “not hard working Mainers.”
