It is NOT a Republican Legislative branch, it is the Senate. Who just happens to be in the control of the Democrats and more specifically Senate Leader Harry Reid.
So you need to start asking WHY Harry Reid wont call for a vote. Let the Republicans all vote no if they choose....it wont stop the confirmation of the nominee, the Senate only needs 51 votes to pass, the Democrats have that all by them selves.
But instead of looking at reality, just keep bashing the other side.
