Elizabeth Warren rises as Joe Biden clings to delegate edge — CBS News Battleground Tracker

This poll tells a story of Elizabeth Warren rising. But not Joe Biden falling.

The former vice president now clings to a narrow lead over Warren in our CBS News/YouGov Tracker estimate of convention delegates – the only count that ultimately matters – with an estimated 600 delegates of all delegates available through Super Tuesday, to Warren’s 545.

Warren has gained delegate share as supporters of other, lower-tier candidates have been switching their preferences toward her. CONT.
