I haven't issued a single opinion on the current crop of candidates yet (that I recall). Still observing. Your point here is important though. Makes one a bit fearful of what an administration would look like! Seems Mitt has some "vetting" issues. Think about judicial appointments, etc.
He appointed more non-Republicans than Republicans to the bench in Massachusetts, including at least one radical gay activist that I know of. Same with executive positions in his administration.
The record ain't pretty.
