The Republican majority in the House of Representatives is about to get even smaller. Congressman Ken Buck, who was already scheduled to retire at the end of his term, announced he's now going to leave Congress at the end of next week. That means Republicans will only be able to lose two votes anytime they want to pass legislation or do anything else along party lines. The official count in the House will now be 431 members, 218 Republicans and 213 Democrats. This is going to make it even more difficult for them to get anything done.
