Here are the latest additions to our round-up of state-by-state general election match-ups: Missouri and West Virginia.

**Missouri:** In the last 10 elections, this key swing state voted with the winner every time. (In fact, if Wikipedia has it right, Missouri has voted with the winner in every election since 1904 except in 1956. Missourians didn’t like Ike?) This time, Barack Obama and John McCain are neck-and-neck with Obama leading 43 percent to 42 percent with 9 percent saying “other” and 6 percent not sure, according to a Rasmussen reports poll conducted June 3. The margin of error is 4.5 percent. The previous Rasmussen poll in early May gave McCain a 6 point lead. McCain is viewed favorably by 55 percent of voters compared to 43 percent who view him unfavorably, and while 49 percent see Obama unfavorably against 48 percent who view him positively. Missouri voters say getting American troops out of Iraq by the end of the next President’s first term is more important than winning the war by 56 percent to 38 percent. Sixty percent believe Obama is likely to do that versus 35 percent for McCain. A mid-May SurveyUSA poll also showed this to be a tight race with Obama leading McCain 45 percent to 43 percent and 12 percent undecided. The margin of error for that poll was 4.1 percent.
