...growling is the last desparate act of a pit dog that's loosing...when he can't do the "deed" and he's failing, so his last bit of hope is "growling"...maybe, just maybe it intimidates his opponent enough so he can stop getting a "beat down"...a good game dog never growls, he just keeps plugging along because he likes the scrap...he just loves it...you understand what I'm getting at?...
He didn't do it on his own. Ciggy didn't. he had a lot of obamabot voters on his side voting more than once...like here:
http://www.punditpress.com/2012/11/f...9-of-vote.html Polling stations where republican poll watchers were thrown out had a 90% turn out, 99% voting for Obama... 30% over Government figures. But these are democrats so it's okay.
