Democratic chances to win back control of the House seem to be running out of time, according to Kyle Kondik, the House editor for the University of Virginia's Center for Politics.

Kondik has just tweaked his election analysis to cut the likely Democratic gain from six to four House seats, 21 fewer than needed to reinstall Nancy Pelosi as speaker.

"Given that the Republicans start from a position of great strength -- Democrats need to net 25 seats to take control of the House -- the GOP remains a heavy favorite to hold the lower chamber of Congress," he said. "The center of gravity in this race -- two sides locked in a close contest -- is clear, and it favors the Republicans."
