Just as Michigan, so goes Wisconsin and Maine. The AP reports"The Republican National Committee is halting presidential ads in Wisconsin and Maine, turning much of its attention to usually Republican states where GOP nominee John McCain shows signs of faltering."
It looks like the GOP is going to focus mainly on Colorado, Missouri, Indiana and Virginia. Florida and North Carolina are also getting some love, but Pennsylvania may be lost, though it's still getting ad dollars. According to the article, "Obama is outspending the joint efforts of the Republican Party and the McCain campaign by more than 2-1."
When you have to focus so much attention on usual gimmes, you can't very well steal any from the other guy's basket.
