There are no, zero, zilch...undecided voters. The folks that claim not to know are not showing up. Undecided is BS.
Every election there is. Thry arr reliable voters. Reluable in that they vote. But their vote cannot be counted on in terms of how they bote. They claim to vote for the person. Then there are the turnout voters. They turn out when motivated to vote for or against someone. But otherwise they don’t engage.
