Limited government conservatives remain disgruntled in Congress, both when in the majority and when in the minority. Republicans campaign on shrinking government, lowering taxes, embracing free markets, and upholding the constitution. But members who actually hold themselves to these promises once in Congress exist only in small pockets.

Senate Majority Leader Mitch McConnell (R-Ky.) has indicated that he will bring an ObamaCare repeal bill to the floor early next week for a motion to proceed. For those not familiar with a motion to proceed, it's a procedural vote that allows the Senate to consider a piece of legislation on the floor.

It's often said that House Republicans have voted to repeal ObamaCare more than 50 times since taking control of the lower chamber in January 2011. Such rhetoric isn't an entirely accurate picture of the votes the House has taken. Yes, it's true that there have been more than 50 votes to repeal, defund, or delay either the entire law or parts of it, but there have been relatively few votes to fully repeal or delay ObamaCare.

The Congressional Budget Office (CBO) has released its much-anticipated score of the American Health Care Act (AHCA). Over the next ten years, the CBO estimates that federal revenues will decline by $882.8 billion as a result of the repeal, delay, or zeroing out of most of ObamaCare's taxes, and federal spending will be reduced by $1.219 trillion. Overall, the deficit would be reduced by $336.5 billion from FY 2017 through FY 2026 under the proposed legislation.

As House Republican leaders try to convince conservatives in Congress to support the American Health Care Act, let's take a trip back in the time machine. Back in November 2003, Congress passed and President George W. Bush signed the Medicare Prescription Drug, Improvement, and Modernization Act, H.R. 1, which created Medicare's prescription drug benefit plan, known as Medicare Part D.
