The parties before and after the White House Correspondents’ Association Dinner, April 28, are at least half the fun of running around town, whether to Vote Latino at the Hay Adams, NPR’s party at the Gibson Guitar Showroom, Tammy Haddad’s brunch at Mark Ein’s house on R Street (the former home of Washington Post publisher Katharine Graham), the newly launched Google party, the Time reception at the St. Regis, the Capitol File party at the Newseum or the MSNBC party at the Italian Embassy. Of course, the pre-dinner receptions at the Washington Hilton are great for checking out the scene. Just show a ticket to the guard at the escalator. And, of course, the main event itself, where the president and Jimmy Kimmel threw out jokes on the GSA, Secret Service, Mitt Romney, dogs and the media. Thank goodness for the McLaughlin Group-Thomson Reuters brunch on Sunday atop the Hay-Adams: a sunny, mellow way to recover from the parties with friends and colleagues. Yeah, it was sort of a nerd prom when “glitz meets geeks,” as one smartie observed, but it’s ours for a few days in April each year.
