They'd do well to remember the law of karma

Allahpundit at Hot Air looks at the possibility that the Senate FHers could extend this simple-majority business to legislation.  He notes:

Democrats should want the taboo against removing the filibuster for legislation in place if only for that reason. If they nuke the rest of it now, the GOP can pass repeal with 51 votes in a few years and say, quite correctly, that they’re only following the rules made by Obama and Harry Reid. Does [pinch-hitting press secretary Josh] Earnest not understand that? Or has Democratic arrogance about Hillary’s supposed inevitability reached the point where they can’t imagine the GOP taking over the federal government until 2025 at the earliest?

Arrogance can lead to recklessness.
