Big government Republicans are much more common than small government Republicans. At least in Washington DC.
Saying that, as noted in the attached article, much good has been done over the last 5 years.
But the GOP-run Congress deserves some of the blame too, because it changed the political context in which Paul was attempting to operate. Instead of pushing for spending reforms by using the debt ceiling as leverage—the only brinksmanship tactic that has proven consistently popular with the public—the once-feisty Republican House just waved the federal debt limit away until 2017. Instead of respecting grassroots revulsion at such crony-capitalist goody dispensaries as the Export-Import Bank, Congress found ways to bring the corrupt beast back from the dead.
