Nah that's crap. Trump doesn't have to become the new norm.
If the American population has any collective sense (I know, I know) there will be a move back to the standard political process after this pretender is gone. Which is still a million miles from good but it doesn't need to continue to get worse.
Getting behind the idea of another celebrity with zero political experience running for the biggest political office in the country (if not the world) is sheer lunacy.
This isn't entertainment, it's people's lives that are being destroyed. Even if you don't acknowledge that because you don't personally know anyone affected.
The two issues aren't related to one another. Trump is obviously a demagogue. That doesn't however mean that politicians are obliged to speak like dull, politically correct androids.
