Mitt Romney tops the latest Des Moines Register Iowa Poll in the closing days before the Iowa caucuses, but Ron Paul and Rick Santorum are poised within striking distance.
The poll, conducted Tuesday through Friday, shows support at 24 percent for Romney, the former governor of Massachusetts; 22 percent for Paul, a Texas congressman; and 15 percent for the surging Rick Santorum, a former U.S. senator from Pennsylvania.
But the four-day results dont reflect just how quickly momentum is shifting in a race that has remained highly fluid for months. If the final two days of polling are considered separately, Santorum rises to second place, with 21 percent, pushing Paul to third, at 18 percent. Romney remains the same, at 24 percent.
Momentums name is Rick Santorum, said the Registers pollster, J. Ann Selzer.

By point of comparison here is the result from 2008
On January 3, 2008, the Iowa caucuses began. The final averaged polling results from Real Clear Politics showed Mike Huckabee at 30%, Romney at 27%, McCain and Thompson tied at 12%, Paul at 7%, and Giuliani at 6%.[7] Among those surveyed in Exit Polling data, 45% cited themselves as very conservative and voted for Huckabee 35% to Romney's 23% and Thompson's 22%. Among those who called themselves "somewhat conservative" (43%), Huckabee won 34% to Romney's 27% and McCain's 18%.[8]\\\
It is my belief that the Republican establishment will be thoroughly shocked at Romney's weak performance coming in with a lower percentage in 2012 than 2008 against a very weak field and will reinforce moves to start an alternative draft at the convention, which because of changes in the primaries from winner take all to proportional primaries will mean that no one arrives at the convention with 51% or anything close to that.
