The big talking points from last night

Candidates were pressed on a number of issues at last night’s Democratic presidential debate. But the standout moments involved topics close to the business community.

On health care:

• Senator Elizabeth Warren, who has moved to the top of some polls, faced more criticism about her universal health care proposal than she has in the past.

• Mayor Pete Buttigieg told Ms. Warren he didn’t understand “why you believe the only way to deliver affordable coverage to everybody is to obliterate private plans.”
