Who is Julián Castro's direct competition for the nomination?

Based on a recurring series of national surveys we conduct, we can figure out who the other candidates competing in Julian Castro's lane are, and who the broader opponents are within the party.

• Those who would be satisfied with Castro as nominee were also satisfied with Sen. Kamala Harris as nominee in 73% of cases. That's not only huge, it's also 17 percentage points higher than Harris' performance among all Democratic voters, meaning that Castro's constituency finds his more popular rival from California seriously appealing.

• Former Vice President Joe Biden, a frontrunner in general, also does well among those who'd be satisfied with Castro, but not to a particularly unexpected extent.
• Sen. Cory Booker and former Rep. Beto O'Rourke seriously outperform their general satisfaction rate among Castro fans. All told, 66 percent of those who'd be satisfied with Castro would also be satisfied with Booker, and 65 percent would be satisfied with O'Rourke. That's 22 percentage points and 14 percentage points, respectively, above their performance among all Democratic respondents.

INSIDER has been conducting a recurring poll through SurveyMonkey Audience on a national sample to find out how different candidate's constituencies overlap. We ask people whether they are familiar with a candidate, whether they would be satisfied or unsatisfied with that candidate as nominee, and sometimes we also ask whether they think that person would win or lose in a general election against President Donald Trump.
