I think those States are trending Democrat because the GOP in those states are not putting up good candidates.
Didn't the last GOP Senator from MT have some ethical issues?
The McCain/Palin ticket may do alot to return respectiablity to the GOP.
McCain mentioned that in his speech, that the GOP hadn't changed Washington, Washington had changed the GOP.
If you look at the MT state legislature compostion where the Dems control the Senate and are one vote away from controlling the House and you have two Dem senators and a Dem governor, something is happening in MT.
