In fourth place? Sen. Ted Cruz (R-Tex.), who perhaps more than anybody embodies the outsider mentality from within the U.S. Senate.
The combined vote total of those four candidates? 65 percent.
The combined vote total for Jeb Bush, Marco Rubio, Chris Christie, Scott Walker, John Kasich and Bobby Jindal -- who all come from more establishment-oriented backgrounds and the first four of whom have at times been considered GOP front-runners -- is 22 percent.
And while the split is more pronounced in favor of outsiders in this poll, it's not a new phenomenon. The Des Moines Register/Bloomberg poll over the weekend showed the four outsiders getting 54 percent of the vote, compared to the latter sextet's 26 percent. That's still more than two-to-one.
The Monmouth poll also asked people whether they preferred a candidate with experience in government or whether they want "someone outside of government who can bring a new approach to Washington."
Fully 66 percent chose the latter. And they are putting their poll responses where their mouth is.
If you're Bush, Rubio or even Walker, that has to be affecting your calculus in Iowa.
