There are two possible explanations:
1.) Gingrich was drunk, or on some drug.
2.) Gingrich is very well aware that he is widely despised by the extremists who have taken over the GOP, and
has been waiting for the right moment to redeem himself in their eyes by saying a bunch of crazy shit about Obama of the sort that they say every day. He knows they're stupid enough to go for it, particularly if he sticks in a signifier like "Alinsky," to which these nuts respond like Cleveland audiences respond to a rock star yelling "Cleveland."
Maybe both of these explanations are right; though I doubt his gorge rises easily, even a hardened player like Gingrich may not be completely at ease with with the Gathering of the Juggalos that is the current GOP, and his use of "factually insane" may indicate that he was, with the aid of spirituous beverages or weed, reaching for whatever concert metaphor he could remember that might be appropriate to such a crowd, and finally settled on Cypress Hill's "Insane in the Membrane."
(Also, his "I may or may not be the recipient of that" suggests that he had to be high.)
Unquestionably
Gingrich has upped the ante for all the squares at the top. Now Mitt Romney must appear at some state fair on a makeshift stage, holding two cylinders, one marked FASCISM and one marked COMMUNISM, and ram them suddenly together, whereupon in a puff of smoke an effigy of Obama will appear and be set upon by local yahoos bearing sticks who will break him open to get at the candy and prizes inside. (It'll be much easier for Tom Tancredo, who will just have to tell his crew that Obama is a goldurn Messican.)
