The Daily Show‘s Jon Stewart can’t figure out who would be conservative enough for this Republican Party.

The far right is opposed to the modest compromise negotiated by Rep. Paul Ryan (R-WI), who is now being called a “sellout” by some. And John Cornyn (R-TX) — the nation’s second most conservative senator — is facing a Tea Party primary challenger who refers to him as “liberal John Cornyn.”

So how about Ronald Reagan?

Nope. Still not good enough.
