Find a mountaintop. Wait for your Savior, it won't be long now. You'll be just as effective from your mountaintop as you are now, and that is not at all. Arnie is now in a position to effect change, but it won't happen if he purposely, metaphorically, slits his political wrists. Cause and effect, action and reaction; stuff dummies don't understand.
It also won't happen if he enacts the same policies that Bustamonte would have, had he been elected. But, I'm sure you'll feel better, knowing it's a Republican stabbing conservatism in the back, and not one of those evil people like DiFi.
If he didn't want to "alienate" California voters on this issue, Arnold could have just STFU, but instead he chose to come out in solidarity with the likes of Sarah Brady. I notice a strong tendency in Arnold to appeal to populist notions to accrue political power, but little tendency to spend that political capital on anything tough. Witness how he is trial-ballooning signing the "revised" driver's license bill.
You follow your celluloid savior, and I'll look to a better one. We'll see who ends up better off.
In the meantime, realize you don't gain ground in politics by parroting the other side's stance. Capitulation and surrender, go along to get along gets you to a place you didn't want to go; stuff even dummies should understand.
