Incorrect, you had to be an Iowan to vote. Also, nobody can really buy votes when there is a secret ballot. None of those providing free tickets could control how the people would vote once they were in the booth.
If you want to know how Romney turned out four thousand voters, ask yourself what tightly organized group he belongs to. (not a criticism of that group, I admire their organization)
I suppose Huckabee bused in a bunch of evangelicals, and Brownback brought in some nuns and priests?
Or do you only mean to smear Mormons? Are they the only religious group devious and underhanded enough to pull off this feat of political skill?
It's a Mormon conspiracy. Right in the Iowa heartland. Where's Governor Boggs when you need him?
