Word of the Day: MIKA Brzezinski (36A: "Morning Joe" co-host Brzezinski) —

Mika Emilie Leonia Brzezinski (/ˈmiːkə brəˈzɪnski/; born May 2, 1967) is an American television host and journalist. Brzezinski co-hosts MSNBC's weekday morning broadcast Morning Joe with former Republican representative Joe Scarborough. // Brzezinski was born in New York City, the daughter of Polish-born foreign policy expert and former National Security AdvisorZbigniew Brzezinski and Swiss-born sculptor Emilie Anna Benešová. Her mother, of Czech descent, is a grandniece ofCzechoslovakia's former president Edvard Beneš. Her father was then teaching at Columbia University, but the family moved to McLean, Virginia, near Washington, D.C., in late 1976, when Zbigniew was named National Security Advisor by newly elected President Jimmy Carter. Her brother, Mark Brzezinski, is an American diplomat and the current United States Ambassador to Sweden since 2011. (wikipedia)

Pretty lackluster, as tributes go. Liz is one of the best constructors on the planet, but this theme just lies there. Bunch of "I HAVE  A DREAM"-related speech stuff. Kind of ho-hum. My favorite thing about this puzzle is ATTACK AD (58A: Aggressive campaign TV spot) — a modern reality that represents the reality of our current political system. Great, modern answer that cuts against the obligatory pieties of today like an indictment. Fill is a bit subpar in places, too—standard for the NYT, but a bit less than I expect from a constructor of this caliber.

I found this a bit harder than normal (though by no means "hard" in any absolute sense) because of PARI- (which I didn't know how to spell: went with PARA) and ONE ALL (which I had as ONE ONE). That made 21A: Matchmaker's match-ups look like this: POIRANGS. I am quite fond of this terribly wrong non-word, POIRANGS. Sounds like an exotic ape … or fruit. But alas, the answer was PAIRINGS. I also stumbled by entering the in-the-language EPIC instead of the crosswordese / technical term no one uses, EPOS at 46A: Long narrative poem. This meant that my Niagara Falls (40D: Niagara Falls sound = ROAR) was making all kinds of weird sounds, most notably FIAR (I typoed the "F" somehow, perhaps instinctively following MLK with JF … K? Who knows? Anyway, slowed down there as well. Time was still quite normalish.

Enjoy your day, especially if you're lucky enough to have it off.
