See post 183 and get your facts straight.
J.D. was statistically tied with McCain for months. Shucks, when the polls were restricted to Republicans only, J.D. was leading McCain.
When I said polls, I didn't mean polls from 4 months before the primary. Do you have access to polls from late July and August 2010? Find them and then you will understand my statement "polls showed JD had no shot at beating McCain." However I will concede your point that JD polled well before he announced his candidacy in mid Feb 2010...and up to 4-6 weeks after.
I don't know if Palin's endorsement beat JD, but I do believe scandal, hypocrisy, 100+ other endorsements from major GOP and AZ state law enforcement figures, plus $21 million is probably worth more.
Instead of answering my question you pointed me to DoughtyOne's post about the effect of Palin's endorsement 4 months before the primary election so I'll try my question again this way...Do you really think Palin's endorsement convinced rats to ignore their own contested primary and vote against JD? really?
