Romney has received the most votes among self-described tea partiers! Of course, he's received the most total votes thus far. In fact, his advantage in absolute votes is a lot larger than his tea party edge is. The following table shows the percentage of each candidate's electoral support that has come from primary voters who support the tea party, as well as the total number of votes, tea party or not, in the states considered that each has received:
|Candidate||Tea party||Total votes|
The presumption that the foundation of the tea party movement is Jack Hunter-style libertarianism is incorrect. Tea partiers are merely more conservative (in the popular, political conception of the term) versions of the GOP's general electorate.
If the tea party was primarily driven by libertarian concerns, I'd expect relative support among members to flow as follows, from most to least: Paul, Romney, and then either Santorum or Gingrich. In fact, it flows in the opposite direction, with the most socially conservative and big government candidates getting the greatest amount of tea party support relative to the support they're receiving from the rest of the Republican electorate, while at the same time, the candidate who is by far the most serious about taking an axe to federal budget is received more coldly by tea partiers than he is by non-tea party Republican primary voters.
It's too bad tea partiers apparently don't realize that the modern bureaucratic state, whether it has a Republican or a Democrat as its titular head, inexorably increases the anarcho-tyranny that political correctness necessitates, inhibits the process of creative destruction, and squelches personal freedoms. The beast cannot be tamed. Our only chance is to starve it.
