He chose her for a reason, and we owed him the courtesy of letting her have hearings. This was a stupid bit of strutting and bloviating by the pundit class, and it has played right into the hands of the Dems.
Miers was not a particularly good choice in my estimation, but our side did not handle the process very well by immediately throwing a screaming fit not even 5 minutes after she was nominated -- that's what is expected of dems. The same non-confirmation of Miers could have been accomplished in a more dignified manner without the juvenile histrionics.
