The Club for Growth shares their list of the ten dumbest votes in the House of Representatives:

MOHAIR SUBSIDIES (Roll Call 383, 2000) - Offered by then-Rep. Mark Sanford, this vote sought to defund all mohair subsidies. Pray tell, what exactly is mohair?

From 1995 to 2005, taxpayers have been on the hook for $40 million on mohair subsidies.

Thankfully, the House sided with King, but 121 members still wanted to keep it up (the subsidies, that is).
