During a televised debate with Democratic opponent Elizabeth Warren, U.S. Sen. Scott Brown, R-Ma., voiced his displeasure with Senate Republican Leader Mitch McConnell, R-Ky., and said he’s undecided on voting for him to lead the GOP caucus.

President Obama is leading in Massachusetts by at least 30 points, and Brown is stressing his role as a moderate Republican with a bipartisan record. Asked if he’d support McConnell next year, Brown said he was undecided and voiced disgust with Congress.

Watch (h/t LEO Weekly):

Brown is engaged in a close general election race against Warren, who is a popular challenger in Democratic circles. In 2010, Brown won a special election with heavy Tea Party support to replace the late Ted Kennedy.
