Committee chairmen

Stories abound about the possible Republican takeover of the senate but what does that mean. It does not mean that they can overturn Obamacare because The President would veto any legislation designed to do that. It takes 2/3rds vote to override a veto. What is important is that the majority party gets to appoint committee chairmen and they in turn determine what goes on in the senate. For example Harry Reid is the majority leader and he currently has 360 bills passed by the Republican congress that he will not bring to the floor for a vote. He then refers to them as the do-nothing congress. Party chairmen wield all the power.
