Joe Biden’s Poll Numbers Are Steady, but Are They Immovable?

Former Vice President Joseph R. Biden Jr.’s presidential campaign has been defined by what it’s not as much as by what it is. He hasn’t made waves with big-ticket policy proposals, and he has mostly avoided skirmishing with his Democratic rivals.

And so, nine months into his campaign, Mr. Biden is in a remarkably similar position to where he was when he began: He’s the presumptive front-runner, despite a lack of agenda-setting plans or breathless enthusiasm from supporters.

Poll results can help us understand why. CONT.
