KANSAS CITY, Mo. — From liberal California to conservative Missouri, there are few places Sen. Elizabeth Warren won’t go this election season. The Massachusetts Democrat is campaigning for Hillary Clinton, for Senate Democratic candidates and for liberal policies.

And she’s banking political capital that she could end up spending in ways that make Clinton and other Democratic leaders uncomfortable.

Already Warren has been laying down markers for Clinton, in public and private, to consider activist progressives over Wall Street allies for appointments to key financial positions like Treasury secretary. The months to come will tell whether Warren serves as ally, antagonist, or both, to a new Democratic president and leadership in Congress.

Warren’s stature has never been more evident. The wind-down of Vermont Sen. Bernie Sanders’ presidential campaign has left her onstage as arguably the most influential liberal politician in the country.

She gets rock-star treatment from Democrats everywhere she goes. “This is bucket list territory. … She is a hero!” Judy Baker, Democratic candidate for Missouri state treasurer, shouted to an excited crowd in Kansas City, Missouri, before Warren appeared last Friday with Senate candidate Jason Kander.
