Among the many dumb and harmful things Senate Republican Leader Mitch McConnell (R-Kentucky) has voted for over the decades -- and there are some doozies, for example, adding trillions to the national debt, creating the unneeded and unaffordable Medicare Part D prescription drug entitlement (2003, Roll Call Vote 457), and, even more outrageously, funding Obamacare (2013, RCV 206) -- one of the dumbest has to be the light-bulb ban (2007, RCV 430).
