Muslim community center + 2 blocks from ground zero
Nazis + 2 blocks from Holocaust Museum
The analogy only works if a Muslim community center is the same as a Nazi party building. That is, the analogy is totally false. The only real question is whether Gingrich (i) really doesn’t know that his analogy is bogus, or (ii) knows but doesn’t care so long as he gets his 30 seconds on all the cable news shoutfests.
