Great news for Mr. Romney.
How is this great news? Rasmussen's June poll had Romney getting 47% in Iowa, this one has him getting 46%. Granted the margin improved by 1% because Obama went from 46 to 44%. But none of the differences between the June and August polls are greater than even half the MoE. It is good news for Romney in that Iowa is maintaining its greater than national swing for Romney, which he needs to have any chance of getting Iowa with his current polling. However, he needs to improve his polling, not maintain it if he is to have a chance to win nationally.
