When it comes to the Ryan Roadmap, I'm with Ramesh Ponnuru (but then thats where you can usually find me). The Ryan Roadmap shouldn't be the GOP's economic platform for 2012. The attack ads practically write themselves, "They'll tax away your employer-provided health insurance, and for when you are older, they'll cut your social security and medicare. But at least they will get rid of the capital gains tax"
Ponnuru is right that people will only swallow so much change. They are also going to want some up-front show of competence from the people who want to reform middle-class entitlements. How about moving the tax code in a more pro-child, pro-parent, pro-jobs, pro-growth direction or making incremental improvements in the health care market. Either of those policies would be the biggest federal level conservative policy change since welfare reform.
The key will be to put together a package of policies that are big enough to matter, but digestible enough not to scare people who know that things have to change, but have alot to lose.
