Notable Quote of the Day

“It may be harder to think of Biden as a factional candidate than Sanders, given that Biden also enjoys significant support among a broad swath of demographic groups within the party, including a majority of African American voters. But he’s nonetheless facing a situation in which, if he did win, he might be a relatively controversial nominee who alienates some wings of the party or has trouble generating enthusiasm that can translate into voter turnout. …

Of course, it’s also plausible that Biden and Sanders experience more opposition than the other candidates because people simply know more about them — they both have high name recognition and long histories in politics. We found that candidates without such histories, like Warren and former Housing and Urban Development Secretary Julián Castro, weren’t really opposed yet by early-state activists or Iowa caucusgoers. This could change, though, as Warren’s new status as a front-runner means a good deal of criticism and media attention will be aimed at her, and the number of Democrats uncomfortable with her as the nominee may well rise.”
