The classic "all politicians suck" defense of Newsom. There is some merit in that defense. Almost all politicians do suck. But I am not moved by a bosides defense. He is worse than the average politician.That's quite the silly statement from someone whose reactions to him come across strongly as "jilted former lover".
You seem to read a lot into both Newsom and support for him, all in the most negative light possible. I'm not sure what put this bee in your bonnet, but it doesn't seem to be explained by anything Newsom has done (when compared to things that other politicians also do on a daily basis).
If it takes a jilted lover approach to sound the alarm on Newsom and get people to realize that he should not be the standard bearer for national democratic politics, it is a worthwhile effort.
