Providing a reason for doing what you do is, in politics, almost as important for doing the thing. Instead of their lame, inside-baseball rationale of “we just don’t confirm Supreme Court Justices in an election year, here’s how Republicans should clarify their opposition to Obama’s Supreme Court nominee:
We cannot, and will not, confirm any Justice to the Supreme Court whose vote would imperil important Constitutional Rights such as the Right to Bear Arms and the Right to Practice Religion.
This would clarify why Obama’s nominees need to be opposed in a manner that reaffirms commitment to Constitutional Principles and resonates with key constituencies of the Republican base.
But, instead, they will probably just stick with that “We’re not going to confirm anyone in an election year” thing that makes them look like a bunch of yammering, out-of-touch, politicians.
