The fate of House Republicans has been in the hands of about 40 out of 246 members. They are the Freedom Caucus — some of the most conservative members of the House, who largely align with the Tea Party movement.
They've been causing outgoing House Speaker John Boehner headaches since he was elected to that position. The irony being that he became speaker when Republicans took over the House with the Tea Party wave in 2010.
And they are not too keen on Boehner's number two — Rep. Kevin McCarthy, R-Calif., who pulled out of the race for speaker this week.
