President Paul Ryan?

Jason Linkins has an article at HuffPo, Late Returns: Paul Ryan 2012? suggesting that since the Ryan budget proposal will be the basis of the GOP economic platform, its architect should carry the party standard in the 2012 presidential election. Since Ryan left his last town hall meeting hastily, through a side door, in a different car than he had arrived in, due to "security concerns," I don't think that's likely to happen.
