In a sign of how brutal the 2014 Election Day has been for Democrats, top House Democrat Chris Van Hollen is now clinging to a small lead in the Maryland 8th congressional district.
Van Hollen, ranking member of the Budget Committee and one of House Minority Leader Nancy Pelosi’s top deputies, leads Republican Dave Wallace, 50.6 percent to 49.4 percent as of 12 a.m. Wednesday.
In 2012, Van Hollen won re-election by about 30 points with 63 percent of the vote.
