Former vice president and ex-Delaware senator Joe Biden
Several polls were taken during the last days of April and into early May. The HarrisX research organization and the Morning Consult firm conducted national surveys while Firehouse Strategies/Optimus commissioned Democratic primary polls in three of the first four nomination venues: Iowa, New Hampshire, and South Carolina. All of these polls produced big leads for Biden in contrast to what we were seeing just two weeks ago.
But, Change Research, in a slightly later New Hampshire poll with a larger sample (May 3-5; 864 likely New Hampshire Democratic primary voters), finds Sen. Sanders still on top, 30-26-12 percent over Biden and South Bend (IN) Mayor Pete Buttigieg.
The HarrisX national poll (May 3-4; 440 registered voters in the US) gives Biden a whopping 44-14 percent lead over Sen. Sanders with all others following in single-digits. The third-place finisher, Mayor Buttigieg has only eight percent support. Sens. Elizabeth Warren (D-MA) and Kamala Harris (D-CA) have seven percent and six percent, respectively, while former Rep. Beto O’Rourke (D-TX) has dropped to just three percent, tied with New Jersey Sen. Cory Booker.
