On the strength of the Des Moines Register Iowa Poll, Mitt Romney has taken the lead in the Iowa Composite Poll.

If this vote turns out as the Composite has it today, Romney could not be in a better position to win the nomination. Meanwhile, Newt Gingrich is facing the same fate as Rick Perry. Rick Santorum has momentum in Iowa, but no where else as he has focused his entire campaign there. It is very difficult to see how he has any path to the nomination without pulling out the win, with an enormous run of fundraising success to follow.

Second tier finishes by Perry and Bachmann should signal their time to exit the race. Huntsman should do the same after New Hampshire.
