I still have no insight as to why Bush would have picked Harriet Miers for the Supreme Court. However, I'm starting to lean towards the explanation advanced by some that it was a distraction leading exactly to where we are with today's expected announcement of Samuel "Scalito" Alito as his "do-ever" nominee. Alito seems perfectly fitted to the religious right-wing-nutjob faction of the Republican Party with the first reporting on his judicial past being that he was the lone dissent in a case that would have required married women to "notify" their husbands prior to getting an abortion.
If you have to ask why that's a bad thing, consider that most happily married couples would discuss the options and make a mutual decision. If the wife doesn't want to notify the husband, there has to be a very good reason; think spousal abuse, whether mental or physical. Of course, really, if you had to ask why that's a bad thing you've probably not been living in the real world for a long, long time.
Some Democrats are already vowing a fight. How much of a fight will the heretofore quiet Dems put up? Will they filibuster Alito who, at first blush, appears well to the right of most Americans? BushCo. is at its weakest point ever; now would be the time to go for the jugular. But will someone step up the difficult task at hand? Who will assume the mantle of leadership now and show us the way forward?
