Next week, House Budget Committee Chairman Paul Ryan, R-Wis., will unveil his FY 2013 budget. Like last year’s “Path to Prosperity,” this year’s House budget will also include sweeping entitlement reform, including the expansion of the premium-support model in Medicare. But that will not be the most controversial part of Ryan’s budget this year.

Thanks to Sen. Ron Wyden, D-Ore., Ryan has bi-partisan support for his Medicare reforms, which are now solidly mainstream ideas. The real drama in this year’s budget will be over the overall spending levels Ryan sets for the next 10 years. Conservatives, like Sen. Jim DeMint, R-S.C., want far less spending than was included in last years plan. DeMint has even said he may not support the Ryan budget if it does not balance in 10 years.
