Other exit polls have shown that conservative Christians voted for Romney more than they did for McCain; it was the "sensible moderates" who abandoned him in droves.
And Romney's vaunted ORCA get-out-the-vote was a disaster, probably foisted by moles within the party or created solely by managers as opposed to IT types.
Read about that here.
Compare it to Obama's get-out-the-vote here; and apparently he had techies from Google and Facebook helping to make the stuff run right.
Finally there was outright voter fraud in Philly and Cleveland, (and likely Floriduh, though I haven't substantiated that to my satisfaction, despite the reports of Miami-Dade polls being open until 1:00 AM...)
Get a grip and put down the Hal Lindsey cult material.
Christians are called to engage the society PROACTIVELY (see Wilberforce in England and ending slavery there...)
As a techie, the Orca story represents mind-blowing incompetence. That’s something that the national party should have had in place, though. It’s not something you want to try to “get right” between August and November.
