The Des Moines Register this evening has released additional details from a poll done on high-profile political figures. The one that Tom Beaumont has just dropped on his blog shows 2008 Republican vice presidential candidate Sarah Palin is in strong favor among Iowa Republicans. But her unfavorability rating among Iowans overall is 55 percent, compared to the 37 percent who view the former Alaska governor unfavorably, the poll showed.

And Beaumont summarizes, “Those feelings are intense: The percentage of Iowans who view Palin very unfavorably is more than twice as large as the percentage who view her very favorably.” Right — those who deride Palin as “Caribou Barbie” do so with profound dislike, while fans will line up for hours to see her in a Dec. 6 Sioux City book tour and not resent the time spent whatsoever.

The part of The Register poll from yesterday shows President Barack Obama’s job approval rating has fallen to 49 percent, down four percent from September and from 68 percent as he assumed the presidency in January. Obama got 54 percent of the vote in Iowa a year ago.
