I should also clarify what I understand you’re still not sure about — I take that to be the “straight GOP ticket”. Is that the remaining question?
This is very specific, “”However, just nine days before election day 2012, Robinson backtracked, admitting he was voting for Romney and a straight GOP ticket. [56]””
I would like to see the source for that, I imagine it was posted here at FR, Wikipedia should link us to it.
