Casten does call out Trump's racist policies (from the article)

“If the president screwed up, at the end of the day he’s got to be gone,” Steven Wood told me after confronting Casten as he was leaving his town hall in Fox River Grove, Ill. 

But Wood remains convinced that Trump did nothing wrong, and he took issue with the way Casten described the president’s claims about Biden, in particular his declarative statement that Trump and his supporters are “actively suppressing facts.” I witnessed the heated exchange, during which Wood and his wife accused Casten of cheapening the political discourse when he derided Trump’s immigration policies as “racist” and referred to Trump’s claims about Biden as “crackpot conspiracy theories.

Casten also notes the following about Republicans

Casten drew applause when said that while he condemns “horribly inappropriate” remarks from members of his own party, “we are far too quick to condemn hatred when it comes out of a brown woman in a head scarf than we are when it comes out the mouth of a white supremacist.”

“People who ignore their morals and their ethics in order to support something or ignore the facts to support a reprehensible morality, I’m not going to pretend to — ” Casten told Wood as a staffer intervened to whisk him away to his next town hall.
