What a fun grid shape today, almost a figure eight. I loved the top and bottom, but found the middle sections much harder to break into.
I thought I was doing very well with CATSCAN and GOATEE gotten right off the bat. Even with LASSOES, I couldn't get going across the top yet (especially with mbaS instead of CFOS). And unfortunately I tried SEAbedS at 20A: Locales for deep investigations? (SEALABS).
I got going again in the SW. I couldn't recall the full name of Allison Janney's character on the West Wing, only that she went by CJ, so that started me off. 44A: Deadline in a western (SUNDOWN) is a very colorful piece of cluing. And how about the excellent misdirection at 47D: Clay, for one (WHIG). That's Henry Clay, of course. Very nice.
I finally got my first long across answer with DOAGOODdeed. Oops. 50D set me right (LSAT). 53A: Turn lemons into lemonades, so to speak (MAKETHEBESTOFIT) is a lovely 15-letter answer. Then, even though CHIFFON (nice) and HEROIN (not so nice) and INERT were clear cut, I couldn't break into the east middle section either. For some reason, ____HEN was opaque to me, even though I thought of Colbert. And NOGUCHI... well. There you go.
At this point, the obvious in hindsight GAMEOFTHRONES occurred to me, and that opened the top section. This is a really strong set of three answers, especially GOTINTOHOTWATER. 1A: Holder of many titles (CARDCATALOG) is very nice cluing as well. I will give it a B+.
Anyway, I erased my mistakes in the middle west section, figured out ARNO and got CJCREGG through crosses. The east section improved when I took out ISsue and replaced it with ISBNS. Good stuff for our library friends.
