I have kept on saying that Dubya and the GOP has time to turn it around since the summer.
Since election 2005 (when the American people kicked the GOP in the balls and Freepdom insisted that losing was in fact winning).
Since the new year.
They can still do it. It would help a bit if they actually tried, though. :-)
The next wave of scandals haven't hit yet. They are expected, from what I can tell, in early spring and played out through the summer/fall.
My prediction: Many Republicans, unable to stomach voting for a Democrat, will go "populist with credentials." That splits the vote and hands it over to the Dems.
