The Republicans gave up any pretense of fiscal conservatism during the presidency of George W. Bush and the associated Congressional leadership of Dennis Hastert and Bill Frist.
The Republicans demonstrated their acquiescence to Obamacare when the House under the leadership of John Boehner refused to use the power of the purse to defund the program. Since taking control of both the House and Senate in 2015 the GOP has not sent a bill repealing Obamacare and passed by both houses of Congress to the president. The GOP has no intention of taking real action to repeal Obamacare because the ultimate goal of the multinational corporations and “too big to fail banks” funding the party is to move the cost of employer paid health insurance from corporate expense to the backs of the taxpayer.
Hence, Republicans in Congress are active collaborators with the Democrat Party in the ultimate quest for single payer government controlled healthcare. They will not do the right thing on healthcare, trade, climate change, government regulation, education, taxes, or the national debt. They are representatives of powerful special interests, not the people.
