Something those on the left need to realize is that the real audience is third party observers who aren't emotionally attached to a political religion. What those people are observing is one of the two major political factions in the USA absolutely losing their minds over minor ***, like stuff common people would make jokes about. Instead of calm rational debate they see shrill media heads exploding and the "true believers" going on and on about what is considered to be complete ***. Those unaffiliated voters just start ignoring the noise after awhile and any real message gets lost and forgotten.
The same people saying "Russian hackers worked for Trump to win him the election", "Obama should fire Comey for investigating the Clitons" and "Trump is a Russian agent and fired Comey over it" are also saying with equal fervor "Trump is evil and selfish because he had two scoops of ice cream" and "Trump is the Antichrist for making off color comments". The unjustifiably extreme reactions just undermine their credibility.
Third party unattached voters don't give a rats *** about which political team is running the country, they just want to live their lives and have jobs. Doesn't matter how much someone radicalizes their voter base, if they can't attract mainstream support from the average American then they won't get power. Trump largely ignored the Republican core and focused almost entirely on those average six-pack-joe's while Hillary focused on her base to the exclusion and open derision of joe-six-pack. Lost her the election and it's been losing liberals power in congress.
Support in California does not equal national support in the USA.
