House Republicans rode into the majority on a Tea Party wave in 2010. Americans were rightly unhappy with the crony corporatism of the Obama administration, the overweening redistributionism of a Democratic Congress, and a myopically narrow appeal to the far left by the Democrat-dominated government as a whole. Corruption in particular was a top issue for voters.
