Sources inside the Senate tell me that the Republican Conference is scared to death of the tactics of Senators Lee, Cruz and Paul - that it is supposedly putting them in a tough spot.Several of the Republicans are using the Manchin-Toomey compromise plan as an excuse to cave on the gun filibuster. They claim that Senators Lee, Cruz, and Paul are running ahead of the conference in their insistence on a filibuster.What they fail to see is that the cloture vote is the vote to stop the gun legislation from passage.Several Republican Senators intend to vote against the filibuster, but then vote against the overall bill. This is too clever by half. The GOP does not control the Senate as the GOP is want to say every time they don't want to fight.Their only power to block a gun control bill is to unite and filibuster.Voting for cloture is voting for the gun control bill because, again, as the GOP reminds us, they are not in the majority. The only way to stop it is to filibuster.
