Whatever Selzer's final poll shows is what my prediction will be. In 2010, their last poll for Senate was spot on and Governor was pretty close. In 2012, they had Obama up 5 while others had it much closer.
Even Selzer missed in 2010, even tough they were closer. Everybody focuses on Colorado, Nevada as D support missed, Iowa is worse. Every election since 2008 pollsters have missed badly to one side.
