Dating: Dana Bash and Spencer Garrett. She’s CNN’s chief congressional correspondent; he’s a L.A.-based actor you’ve seen in a million shows and movies (“House of Cards,” “Iron Man 3.” “Mad Men” “Casino Jack”) even if you don’t know his name (Garrett’s been known to describe himself, helpfully, as “the guy from the thing”). He’s also a news junkie and was a Bash fan before the two were introduced about six weeks ago by mutual friends Jack and Susanna Quinn. The new couple was spotted looking cozy at both the French embassy’s Bastille Day celebration and the Kennedy Center’s “Book of Mormon”  this weekend.
