I've never said that Kavenaugh is unfit for office based on the sexual assault allegations. If the Senate had any honor they would at least investigate the allegations so that they could be honestly taken into consideration before blindly confirming him. If the guy is a real creep (which is a real possibility, given the recent reports that he screened for law clerks that looked like 'supermodels') or seems to be hiding something (e.g., not asking the White House to launch an FBI investigation to clear his name), we don't really need his ilk on the Supreme Court (but apparently Republicans do, or they may have given up by now in finding any justice at all that isn't also a potential sex offender).
But as has already been pointed out, he's unfit for the Supreme Court for other reasons. In fact this is exactly what

Claire McCaskill said when she announced she'd be voting against his confirmation earlier this week.
