ARIZONA
Rasmussen. 7/18. Likely voters. MoE 4.5 (5/24 results)
Kyl (R) 53 (52)
Pederson (D) 34 (35)
This race is barely hanging on to the third tier, if it even deserves to be on there in the first place. In the governor's race, Napolitano has an equally big lead, 52-37.
MICHIGAN
Rasmussen. 7/25. Likely voters. MoE 4.5% (6/7 results)
Granholm (D) 42 (44)
DeVos (R) 48 (42)
Polling in the Michigan governor's race is all over the place, but no matter what poll you look at, Granholm is clearly the most endangered incumbent Democratic governor this fall.
