Restoring the filibuster is actually a good thing. If Republicans do take control of the Senate, they will control the calendar, but not by a big majority. Remember there are squishy lib/moderates like Goober Graham and Susan Collins and Juan McLame, who will happily cross the divide to confirm democrat nominees. Restoring a filibuster will allow a small minority of conservative Republicans to muck up the destructive force of the obama agenda.
McConnell would probably do a power sharing agreement with Reid like Lott did with Daschale.
