I understand what he's saying.
"Should a justice resign this summer and the president move to name a successor, actions that will occur just days before the Democratic Presidential Convention and weeks before the Republican Convention meets, a process that is already in doubt in the minds of many will become distrusted by all. Senate consideration of a nominee under these circumstances is not fair to the president, to the nominee, or to the Senate itself.
"Mr. President, where the nation should be treated to a consideration of constitutional philosophy, all it will get in such circumstances is a partisan bickering and political posturing from both parties and from both ends of Pennsylvania Avenue. As a result, it is my view that if a Supreme Court Justice resigns tomorrow, or within the next several weeks, or resigns at the end of the summer, President Bush should consider following the practice of a majority of his predecessors and not — and not — name a nominee until after the November election is completed."
and unless Obama made a nomination after the November election, and McConnell failed to take action on it, your point is moot.
