Another day another nail in McCain campaign coffin.

From the Carpetbagger Report:

Less than a month ago, with his campaign in free-fall, John McCain’s presidential campaign circulated talking points to supporters, explaining the skeleton of the senator’s comeback plan.

In a nutshell, the strategy was premised on McCain excelling in three early-voting states: Iowa, New Hampshire, and South Carolina.

Success in these three states would get McCain back on track, and victory would beget more victory. The plan looks a little shaky in light of the senator’s wholesale collapse in Iowa.

[A] new University of Iowa poll finds that McCain is at all of three percent in that state. Incredibly, this onetime presumed frontrunner is behind even Sam Brownback and Tom Tancredo, who each have four percent.

Meanwhile, Mitt Romney leads the field with 27%, followed by Rudy Giuliani at 11%. And in third place is Fred Thompson — who only just recently announced that he would be making his first visit to the state.
