Sen. Rand Paul’s bid for the GOP presidential nomination has lost some steam, thanks to the political establishment’s disdain for his small-government positions. But the Kentucky senator’s crusade to shrink the size of the federal government is still going strong.

The presidential hopeful this week introduced two pieces of legislation aimed at scaling back runaway federal spending.

One of the bills would require lawmakers to clearly identify the objective of new spending legislation, thoroughly investigate potential duplication of existing programs and consider less costly alternatives before funding could be released. The proposal, which has the backing of Republican Sens. Mike Enzi of Wyoming and Jeff Sessions of Alabama, would also make it more difficult for Congress to authorize spending for new projects for periods of more than four years at a time.

According to Paul, the effort would make lawmakers repeatedly revisit costly legislation to make sure taxpayers aren’t funding once-effective programs that have exhausted their usefulness.

“We cannot afford to keep spending taxpayer dollars on expired programs and ones that are never reviewed. My bill will end expired programs, require Congress to review the need for programs before spending more money, and make sure we are only using tax dollars on things that make sense,” the senator said.

Paul’s other bill, the Duplication Reduction and Scoring Act, is specifically designed to reduce the size of government by ferreting out and eliminating programs that duplicate the efforts of other government initiatives.

Paul says the legislation could deliver near instant savings of $10 billion by requiring the president to eliminate and consolidate government programs the Government Accountability Office has already pointed to as duplicative within 150 days of the bill’s passage.

The legislation would also require the White House to submit to Congress further proposals to reduce duplication of government programs.

“Our nation cannot continue to pile debt on top of debt, mortgaging our children’s future for wasteful spending today,” Paul said.
