Miers was compared to Caligula's horse, and denounced by luminaries on the right as unacceptable because they do not know her. This is nothing like any reaction to a nominee in memory. And if there is any precedent for the president’s own supporters to turn on a SCOTUS nominee in such a fashion, I am unaware of it. In fact, I am trying to recall a single instance of any high profile nominee ever being treated in such a fashion by members of the nominating president’s own party.
