Massive Tsunami Coming for GOP?

I know things are going to be dreadful for Democrats (and deservedly so!) but this would be outright crazy if true:

According to the latest NPR Battleground Survey 86 Republican candidates are either tied or ahead of their democratic opponent in democrat-held districts.

Obviously, the GOP will have some districts that fall as well, but it seems that Americans are finally waking up to the absolute disaster of Obamanomics. I just pray it's not too late already.
