Very true.
There is no more Democratic county than New York county which is Manhattan. In the 1980 election Carter v Reagan, the polls were much like they were today. Carter seemed to have the edge. In 1980 as today, there were unprecedented long lines of people waiting to vote. Vincent Albano, the late Chairman of the New York county Republicans chatted with people on those lines. He commented that he never saw people so eager to throw a President out. Albano was right. The polls were wrong,Carter lost, Reagan won big. IMHO people have come to realize that Biden is corrupt and the Democrats are bad for the country. It is why,regardless of party, they are lining up to vote for Trump.
