Only Republicans have become more extreme

From the column: “For the most part, though, the Democratic agenda remains decidedly center-left: Raise taxes on the rich, and use the money to help the middle class and poor. Protect civil rights. Expand educational access. Regulate Wall Street, and fight climate change. Expand health insurance using the current system. And compromise with Republicans when necessary.
The radical agenda is the Republican agenda: Make climate change worse, unlike almost every other conservative party in the world. Aggravate inequality. Sabotage health-insurance markets. Run up the deficit. Steal a Supreme Court seat. Keep dark-skinned citizens from voting. Protect Trump’s lawlessness.”
