there is the disconnect. The guy trying to truly change the system can't win due to inertia. Moreover, once elected, he has to live with the idiots in congress.
Until we find a way to let public sentiment transition toward vilifying the free lunch crowd (on both sides), there is no fix. We're choosing the lesser of evils until entitlements break the system. Until them, politicians will find new ways to entitle more and people will continue electing them.
Forcing any candidate into the mix isn't going to change that. Popular opinion has to move toward entitlements loathing.
