My new Bloomberg Opinion column is about Senator Elizabeth Warren’s vulnerabilities on policy issues in a general election. The fact that she has positioned herself so far to the left would be a problem for her next November. But the specific left-wing stands she has taken could prove especially damaging. It’s a lot of risk for Democrats to take on behalf of an agenda that is probably not going to be viable even if they win.
