The Des Moines Register poll covered Tuesday through Friday. The results: Romney 24% Paul 22% Santorum 15% Gingrich 12% Perry 11% Bachman 7% According to the Register:  If the final two days of polling are considered separately, Santorum rises to second place, with 21%, pushing Paul to third, at 18%. Perry spent millions of dollars on media in Iowa and has nothing to show for it. He ran anti-Santorum spots and they only increased Santorum’s percentage. Santorum’s success is almost entirely due to his endorsement by evangelicals. He currently stands fifth in the state, a point behind Gingrick. The three leaders are uncatchable. Perry has said that he would continue in the race if he comes in as high as fourth in Iowa. He may achieve that, but it won’t be by much.
