I don't know what his track record is. Every time I hear him I get the impression he lives in the NY/Washington Press echo chamber. He make those general statements, "The American people feel/think.....", and they NEVER describe me.
Bingo! Sabato has been in the beltway way too long and has no idea what people in the rest of the Country are thinking. His analysis has been flawed for sometime as he sounds just like the rest of the DC Beltway on the TV. They don't have clue about Middle America or they like to call us -- "flyover country!."
