Am I the only one who thinks the undecideds across the board are way too high for this time of year? Lots of 42-39 or 40-41 polls seem very unenlightening given that we already know all of these races are competitive. By comparison, I think Djou had 45% in the poll showing him behind.
Some voters may be too embarrased to admit that they have no idea who the candidates are, and thus say they are undecided, when really, they will just be voting a party line. Or maybe a lot of voters are cross pressured, and genuinely undecided. Or maybe the polls are flawed. I don't have a clue.
