Nonsense.
Recent polls put him about even with Clarabelle. That's better than most of the GOP Senate candidates that the NRSC and Rove PACs will spend millions on knowing in advance that they are the really lost causes. The GOPe are just stuck on stupid and stubborn.
I understand your support for Akin, but you are being a little selective in your citing of polls. Did you include Rasmussen of 12 Sep in your calculus? (M 49 A 43)
McCaskill has a boatload of money to saturate the KC and StL markets with ads reminding the voters of Akin's words. Akin will lose big in Platte, Clay, and Jackson counties, and in the St. Louis suburbs outside of Chesterfield. This is just not going to happen and its probably too late to do anything about it.
