Pinellas county, here. We are the most population dense area that is not solidly blue or red.
Maybe that’s the logic. But I am not sure that it really follows. The fact that Miami usually votes Dem doesn’t mean that it won’t decide the election. If the voters don’t vote for Hillary, or don’t vote, then it may decide the election.
They have “surrended” to the democrat minority-slaves-mind-numbed-idiots in certain counties holding the major cities: Atlanta (Fulton county GA), Miami, Philadelphia, Chicago itself, Boston, DC, etc. and are trying to figure out if the suburbs around the lost cities are going to be swamped by illegal aliens and duplicate voters being bussed out from downotown.
They probably means Pinellas still counts because Jacksonville and the Miami area cancel out each other.
