Obama is at around 61 cents in both electronic markets
You are aware, are you not, that the Obama campaign is using its illegal foreign contributions to juice Intrade & IEM?
You should be aware that all four of the "tossup" states you mentioned are allocated to Romney now when RCP makes its NTU map. Romney is likely to win both the popular & electoral college vote. He's tied in OH, but doesn't need it to win.
How, Numbers Ninny, do you come up with 52% for Obama when the incumbent can't stay over even 47% in the RCP poll average? Romney remains up 6 points in the Gallup Tracking Poll, well over statistical significance levels.
In any case, win or lose, Romney should pick up at least 261 EVs, forcing your larda$s off this board forever. That's his present count on the NTU map. Without tossups, he's ahead. The remaining tossups, like OH, are trending toward him.
