That's only 2 years with no primary challenger, if the political fortunes of the Tea Party wane you can bet he'll see a challenger sooner or later. We're discussing a 6 year span here, career politicians can potentially spend decades in office depending on how little their constituency changes and how happy their constituency is with their voting record. The second part is critical as it's not usual to have a vote by vote explanation that could be used as fodder by either a primary challenger or a challenger from the other party.

Like I said, I admire the guy, especially if his libertarian-ism extends to areas that dovetail with the GOP and Tea Party on social issues like gay marriage or marijuana legalization. Coming out against SOPA was good but you never know if it was authentic or if he just saw which way the political winds were blowing.
