… Biden has three advantages in this primary: association with former president Barack Obama, relative policy moderation and perceived electability.
It’s basically impossible for anyone to detract from or surmount those first two qualities. Biden was Obama’s vice president for eight years — he’s more closely linked with Obama than anyone other than Michelle, Sasha and Malia — and Obama is still popular among Democrats. And Biden has, for better or worse, spent decades building a left-leaning, but not radical, reputation and voting record. That’s likely helping him grab voters who see themselves as more moderate.
But Biden’s other strength — electability — is assailable. The easiest way to prove that a candidate isn’t electable is to beat them in an election. And Warren could do that in Iowa. CONT.
