No. Making a few Dems part of your team of scores of advisors is not worse -- or, to get back to my original point -- not more "lefty" than endorsing opposing party political candidates in contested general elections.
You're entitled to your view. I just cannot believe that you wouldn't be far MORE up-in-arms if you had learned that Arnold had endorsed or given $$$$ to prominent Democrats, esp. recently. Sorry, not buying.
