As long as people (and Congress) think spending with abandon has no consequences this will continue. There has been nothing “conservative” about the GOP and spending for more than 2 decades now.
(From The Conservative Review)
…following two years of GOP trifecta control of the House, Senate, and White House, spending for the first six months of this fiscal year is 13.7 percent higher than during Obama’s final year. Despite the best job market in decades, the debt under GOP control has surged even higher than under Obama, putting to rest the notion that a good economy can grow its way out of a spending binge this deep.
