"Get your facts first, and then you can distort them as much as you please." (Mark Twain)
My guess is that Janice Rogers Brown will be the nominee - she's black, she's a she (thus assuring that the Democrats will get slimed with accusations of being both sexist and racist when they oppose her), she's completely full-tilt bozo and so satisfies the Dobson contingent, and she just got confirmed to the Court of Appeals - which means that, in addition to the racist/sexist malarkey mentioned above, Democrats will look like "flip-floppers" if they take her on (as Kagro X put it at The Next Hurrah
, the charge will be that Democrats voted for her before they voted against her).
Of course, that last accusation has the added strategic benefit of being true. The Jackass Party is
"flip-flopping" if they suddenly develop principles, having so recently sold out said principles so very cheaply. They got played like fiddles, and now it is the rest of us who will be singing the blues.
