Hmmm. I've been noticing a lot of remarks about Romney's remark that Gingrich is unreliable and "zany." So I looked up the word, and found: "Zany is currently in the top 1% of lookups and is the 2#1 most popular word on Merriam-Webster.com." I've begun double checking definitions in my incipient dotage, and found that zany was not a good word to describe Gingrich unless you wanted to imply that he's a buffoon. That's now how I would think Mitt thinks of him, because it suggests that he is being deliberately clownish to get laughs. If one equates zany with being a little nuts, that might be in order, as it would for Ron Paul who hasn't been able to bring his political views up to date since at least the 1930s, when the GOP was isolationist, along with most of the nation. Newt is crazy like a fox, though, and he's capitalizing on the fact that conservatives hate the news media and, for the time being, have been brainwashed to hate Mitt Romney. His ability to refer to recondite historical points lets him get away with a lot of nonsense that conservatives would normally laugh to scorn. If you think Obama's bullet train envy is goofy, one would assume that the idea of building mirrors in space to light earth's night side or moon bases to mine materials would seem beyond our reach as well, but Newt can advocate such things because he is Not-Mitt, which seems to be a litmus test for the GOP this year. It's as though they'd rather have 4 more years of Obama than support Romney.
