This poll confirms Montana's status as a tossup state.
R+5 during Obama's convention bounce simply confirms a state that will vote Romney in the upper single digits if he's losing and by double-digits if he's winning.
This isn't a convention bounce, its permanent. This poll was taken over the last two days and shows that the Romney campaign is tanking nationally. Obama is heading toward a double digit win nationally and that's why Montana remains a tossup.
Er, no, it's a convention bounce, a fairly weak one at that considering history, and one which considering some other recently released polling (O+11 in Washington, R+9 in Arizona) indicates is very likely already receding.
Short some sort of rally-round-the-flag cataclysm a la 9/11, Montana is safe for Romney.
