10/23: With no toss ups, meaning just looking at who is ahead as of today according to RCP, and giving it to that candidate, Obummer/ol' Joe have 281, and Romney/Ryan have 257. There are many, many, many ways for Romney/Ryan to get to 269 (remember, they win the tiebreaker in the House) or the preferred 270.
This is very clear. If Obama loses Ohio, it's over; andeven if he wins Ohio, he is not out of the woods, because he is very narrowly ahead in several blue states (esp. WI, IA, NV, NH, and several more). Dear Leader has no margin for error as all momentum points to Romney.
Clearly Ohio remains the best path to victory for Romney/Ryan, but it is not the only path.
