it's been crystal clear now for 30 years that Republicans really only care about the budget when they're out of power. Reagan and both Bushes ran as strict budget hawks, but once in office behaved as if deficits simply didn't matter.
Ironically, the ONLY president who made good on the perennial Republican promises of cutting spending, making govt. smaller and cheaper, reducing deficits and getting us on track towards a balanced budget was a Democrat! If Bill Clinton had been president one more year, we would have had a balanced budget. When GW Bush came to office, he simply could not wait to undo all the good work Clinton had done. Almost his first act in office was to call for a big tax cut, just for the richest Americans.
Presidents and congresscritters, they know their power comes from spending. BOTH parties desperately want to spend money to buy votes. They spend it on different things to buy the votes of different demographics, but it's the same thing.
But the Republicans, I think, abdicated their place as The Party of Fiscal Responsibility. Ronald Reagan ran for president for eight years by bashing the national debt, but once in office he TRIPLED the entire pre-existing national debt. GW Bush only doubled the debt, but it was a lot bigger by then. And that nonsense about Obama spending more than any previous president, or even all presidents combined, it's amazing how often you hear that. As if just repeating it over and over could make it true.
