The man is a known as "difficult" with your usual assortment of pejorative qualifiers. Treat with caution. More interested in his opinion than those of the parties. Wishes he was a federal judge and acts accordingly (he was once in the running, didn't make it). Gets off on power.
In short, mercurial. If he's for you, great. If he's not, that's really unfortunate. Mood highly variable. YMMV.
