The Constitution specifies specific instances in which a supermajority is required.
Voting in the Senate (with the stated exceptions of ratifying treaties, convictions for impeachment, and passing proposed Constitutional amendments) IS NOT one of them.
Get rid of the filibuster.
Nuke it.
Send the ashes to the dustbin of history.
I can live with that.
I'll take my chances when the other side wins, which in time they will.
But right now, this is war.
And this time WE have to win.
The old rules don't apply any more, because the OTHER SIDE has made it plain that they won't LET THEM apply.
Well ok... fine.
We'll play their way.
To win.
Even if it means stepping on toes, traditions, and hurting a few feelings.
