Aaron Blake: “A new poll from Stanley Greenberg of left-leaning Democracy Corps provides some more encouraging signs for Warren. It tested both her and Biden against Trump, seeking to find out how the leading candidates from the party’s two flanks might compare in a 2020 general election. The answer is: pretty similarly.”

While Biden leads by eight points (49-41) in a race that includes Rep. Justin Amash (I-Mich.) as the Libertarian nominee, Warren leads by six (49-43). What’s more, Greenberg finds that, while Biden does better among independents (+10 vs. Warren’s +5), Warren consolidates Democrats better (getting 90 percent of their support vs. Biden’s 86 percent). And while Biden gets 21 percent of Republican moderates, Warren gets a respectable 15 percent.”

“Perhaps most importantly for Warren, she actually does just as well as Biden among working-class white voters. Both trail by 19 points with a group Trump won by 27 points in 2016 — a margin he’ll probably need to match in 2020.”
