The lights in the Capitol Hill suite of GOP House Whip Kevin McCarthy (Calif.) stayed on past midnight as more than half a dozen aides shuffled between his offices and those of other GOP house members.

From outside the building, they could be seen conversing as cable news coverage of House Majority Leader Eric Cantor's shocking defeat in a Republican primary in Virginia played on at least one television screen behind them.

McCarthy -- who aides insisted had left the Capitol Building earlier in the night -- is widely expected to mount a run for House majority leader.

"No one is a writing a VA story tonight," an aide to another GOP house member declared as he walked past House whip's bustling suite around 11 p.m.

By midnight, some McCarthy staffers had left for the night, but several others were still coming in and out the suite. All declined to talk to a Post reporter.
