Republican efforts to take back the Senate – already complicated by the controversial campaign of Todd Akin in Missouri and a tight race in Massachusetts – could face another challenge in one of the most unexpected of places.
In Arizona, Democratic candidate Richard Carmona is polling surprisingly well against his Republican challenger, Rep. Jeff Flake. The RealClearPolitics average of polls puts Congressman Flake up by 2.3 percentage points, 44.3 to 42 percent.
On Wednesday, Mr. Carmona's campaign released a poll that suggested Carmona was actually ahead, 47 to 43 percent. Within hours, the Flake campaign countered with its own poll, suggesting Flake was up 49 to 43 percent.
"All you can say at this moment is that it's a race worth watching," says Larry Sabato, a professor of politics at the University of Virginia.
