Joe Biden should watch (the film) and be like Paul Newman in "Cool Hand Luke," in to tonight's debate. Don't be like "angry grandpa," being too aggressive. In that case the voters will bail on him. Be like cool but firm. Cool Hand Joe.
Corey Booker and Kamala Harris need to tread lightly in tonight's debate because if it looks like they're ganging up on Joe Biden, they will alienate Independent and Moderate voters.
They need to ask themselves if they are ready for the blow back that will inevitably happen (regarding their records) if they attack him. Just saying. However, if Kamala or Corey won the nomination, I would vote for them over Donald Trump any day.
I don't like the other candidates except for Julian Castro. Next time please get your transgender facts correct. But he meant well.
