Is It Unethical for Democrats to Promote Crazy as Republicans?

Is it ethical for democrats to promote crazy as republicans because they think it would be easye to beat in hversal emboy used to encourage republicans to vote in democratic parmberries. In maryland this year, just a week ago, the democrats really helped right wing gumatorial nominee dan cox defeat the candidate of the popular, outgoing republican governor, larry hogan. Is certainly not unethical, and it's been done by both parties lots of times. I'm old enough to remember 19 66, democrats in california tried to hurt the popular san francisco mayor, george christopher, who was running in a good mator primary.
