Wisconsin Gov. Scott Walker is “surging” — all the way up to 16 percent in a new Des Moines Register/Bloomberg poll of potential Iowa caucus-goers. And he’s the second choice of an additional 9 percent of voters. But while the Des Moines Register poll had a lot of politicos talking up Walker over the weekend, it isn’t evidence he’s the new front-runner in Iowa. Instead, the survey is (more) evidence that the GOP field is historically divided. CONT.
