“Today, the Senate will vote on a bill that will add $1.5 trillion to the debt over the next 10 years.” That was the reason Senator Rand Paul served as a one-man blockade on Thursday: to delay a vote on a new short-term funding bill that would increase spending. “This is a large amount of money, and something that we should be very wary of.” His efforts briefly forced a government shutdown. “Don’t you remember when Republicans howled to high heaven that President Obama was spending us into the gutter, spending us into oblivion. And now Republicans are doing the same thing.” It wasn’t long ago that fiscal responsibility was a frequent Republican rallying cry. Here’s what some in the G.O.P. were saying when President Obama was in office. “Congress is spending money in a way that would give drunken sailors a bad name.” “We have been spending way too much.” “Washington is full of big spenders.” “Let’s reject runaway federal spending.” “Too much unnecessary spending.” “Cut wasteful spending.” “We need to quit borrowing.” “And borrowed too much.” “The biggest deficit on future generations.” “What we heard today was not fiscal leadership from our commander in chief.” “Our debt represents a national security vulnerability.” “The debt limit being raised without fundamental reform is just a bad idea.” “Democrat budget will double the national debt in five years, triple it in 10.” “After the economy recovers, we should be on a path to a balanced budget.”
