What’s Brewing: Santorum compares marriage to a napkin; Bachmann likes pro-slavery books

Your weekday morning blend from Instant Tea:

1. Anti-gay GOP presidential candidate Rick Santorum on Monday compared marriage to a napkin to explain his opposition to same-sex marriage. And no, we’re not kidding. It’s perhaps the most ridiculous anti-marriage analogy since Texas Sen. John Cornyn hatched his box turtle. Watch video of Santorum’s remarks below.

2. Meanwhile, ThinkProgress revealed that a book saying blacks were better off under slavery once appeared on GOP presidential candidate Michele Bachmann’s “must-read” list. Is it any wonder that Texas Gov. Rick Perry will be considered a frontrunner if and when he enters the race? Who wouldn’t be? Too bad my puppy is a Democrat.

3. A gay couple is suing a California amusement park for allegedly displaying a photo, taken of them riding a roller coaster, with “Were [sic] Fags!” written on it.
