Here are the latest updates to our state-by-state general election match-ups, all from Rasmussen Reports. All had a margin of error of 4.5 percent.

– **Iowa:** Barack Obama leads John McCain 44 percent to 42 percent with 8 percent choosing “other” and 5 percent not sure in a survey conducted May 12. McCain edges Clinton 45 percent to 42 percent with 9 percent preferring other and 4 percent not sure. The figures for Obama and McCain haven’t shown much movement since February. Fifty-three percent of voters view Obama favorably compared to 51 percent for McCain, but that represents a 7 point drop for the Republican.

– **Arkansas:** McCain leads Obama 53 percent to 37 percent, while Clinton bests McCain 53 percent to 39 percent in the state where she was First Lady. McCain’s margin over Obama is due to 92 percent support among fellow Republicans, 38 percent support from Democrats and 24 percent from unaffiliated voters. Obama’s favorability rating here is only 38 percent. McCain’s is 57 percent and Clinton’s is 60 percent.

– **Washington state**: Obama leads McCain 51 percent to 40 percent, compared to the 5 point lead he held in the previous poll. Obama’s favorability rating is 57 percent, while McCain’s is 49 percent – which, as in Iowa, is a 7 point drop for him. A SurveyUSA poll conducted May 12 had Obama ahead 54 to 42 percent with a 3.9 percent margin of error. Clinton leads McCain by 49 percent to 45 percent. Obama runs far ahead of McCain on the issues of the economy, environment, health care and Iraq while McCain leads Obama by a wide margin on the issues of terrorism and immigration.
