I'm thinking that these oversampled Democrat polls will lend weight to Democrats stealing the "close" states, especially if that state has a Democrat Secretary of State. Remember Soros and his Secretary of State Project - "It's not the people who vote that count. It's the people who count the votes." (Josef Stalin)
Well OH, FL, and VA all have GOP governors and while I don’t know about the others, OH has a Republican Sec of State.
