In the first poll conducted entirely after Joe Biden announced he is running for president, he appears to hold a commanding lead among the 21 candidates vying for the Democratic nomination.

The CNN poll surveyed Democratic voters and Democratic-leaning independents and shows Biden’s announcement gave him an 11-point bump. Nationwide, 39% surveyed said that the former vice president is their top pick for president, that is up from 28% who said he was their first choice when the same poll was conducted in March.
