Look at it this way: Dick Morris is an opinion columnist, and his only stock in trade is his alleged brilliance at knowing how elections will go.
The only way he can make a buck in a limited niche like that is to ride the waves as they come, and pretend that he knew all along what the next 12 waves will be like.
At best, Morris has only a marginally better idea of the next wave than you or I do. Where he makes his money is in convincing enough folks that he's not making up everything beyond that.
Good analysis. That raises the question, though - does he believe his own BS?
Let's say the Dems win one or both houses. How would this affect SCOTUS choices if Bush gets one more selection? Couldn't he still get a conservative judge thru the senate even with a Dem majority? If Pelosi and crew proceed with impeachment, how would that affect the 2008 GOP choice?
Could there be a backlash against the Dems or make it easier for Hillary?
