Clinton did not mean to make the comparison but if Biden is being compared to her it does not bode well for Biden in November.
During the interview, Clinton accidentally revealed that Biden's chances of winning the White House are slim given he's built a similar coalition to the one she had in 2016.
“What Joe’s victories on Super Tuesday showed is that he is building the kind of coalition that I had basically. It’s a broad-based coalition. I finished, you know, most of the work I needed to do for the nomination on Super Tuesday, and then it kind of lingered on. And I think Joe is on track to doing exactly the same thing, putting together a coalition of voters who are energized," Clinton said.
Clinton's so-called "coalition" failed on Election Day 2016 and a lack of support led to the crumbling of the usually reliable "blue-wall" of Wisconsin, Michigan and Pennsylvania.
If Biden has built a coalition like the one Clinton had, which for some reason she's touting as a success, then he's bound to lose to President Trump in November.
