The GOP is playing a dangerous game by threatening to change the rules of the Senate. The GOP claims the president deserves an up or down vote on his judicial nominations. If that is true, many more judicial nominations under Clinton never got an up or down vote because they were bottled up in committee. If the objective is an UP or DOWN vote, the tactics of the Republicans during the Clinton administration to prevent a vote through committee is just as much of a problem is holding up a vote in the Senate through filibuster. The end result is the same in both scenarios - no UP or DOWN vote.
Only nine of the Bush judges out of over 200 have not been approved by the Senate. If the Republicans force this change of the Senate rules, I hope to see the day when the Senate is controlled by the Democrats and they have to live with the change they are attempting to force upon the Senate. The old saying , "Be careful what you asked for " may come back to haunt the Republicans.
