By way of explanation:Obviously Biden's bounce is the big news in the several polls out this morning but some other themes too:— Nate Silver (@NateSilver538) April 30, 2019
* Mayyyybe a little momentum for Warren?
* Pretty bad numbers for Bernie. Polling in the mid-teens with 100% name recognition is not very good.
* Buttigieg momentum slows?
Begun, the conspiracy has...CNN 2020 Democratic poll:— Josh Jordan (@NumbersMuncher) April 30, 2019
None of the other 4,000 candidates top 2%
Biden jumped 11 points after announcing his candidacy in the CNN poll, which is troublesome for Bernie who didn't get that kind of bounce.
