You think Arkansas is a tossup? That seems unlikely, to say the least.
Rasmussen will soon release AR and WV polls that will include Obama vs. McCain for the first time.
I expect something like:
WV: McCain+5 against Obama, McCain+3 against Clinton
AR: McCain+5 against Obama, Clinton+3 against McCain
Arkansas is a Southern state with a low black population and which is the home state of Hillary Clinton (in reality), giving her 70% of the primary vote. I'd be extremely suprised if they went for Obama in the general election.
WV and AR are only swing states/Dem states if Clinton is the nominee, period.
