The former Majority Leader, Harry Reid, had the power to decide what bills would come up before the Senate and he certainly used that power to the utmost. I believe the end result was that Obama rarely even had to threaten a veto because bills that displeased the Democrats rarely reached his desk. Now times have changed. The Keystone Pipeline bill is the first example. Senators will be forced to declare themselves publicly by the way they debate and vote on the bill and the President will be forced to to either accept the bill or veto it when it arrives on his desk. This is as it should be. I believe it is called “regular order” of the Senate.
