I like playing poker. Texas Hold’em in particular. Ever since I saw Matt Damon draw John Malkovich into going all in at the end of “Rounders,” I’ve been hooked. And, judging by the increased tournament stakes, ESPN replays, and sheer number of professional players, many others have, too. Apparently, that also includes the key players involved in the selection of the next associate justice of the U.S. Supreme Court.
