Shifts in recent polls have shaken the top of the 2020 Democratic primary field, though the top contenders to face President Donald Trump have not changed with a little more than two months until nominating contests start.
South Bend, Indiana, Mayor Pete Buttigieg has climbed to leads in polling averages of the Iowa caucuses and New Hampshire primary, the first two contests in February,according to RealClearPolitics. Even so, former Vice President Joe Biden has kept his edge in surveys of the Nevada caucuses and South Carolina primary, the two other key early states.
Through the ebbs and flows at the state level, Biden has kept his grip on the national polling lead. While the surveys have their limits because voting takes place in states, they capture a broader snapshot of the race.
As voting finally approaches following months of campaigning, a four-person crowd has emerged at the front of the pack in national and early state polls. Biden, Sens. Bernie Sanders, I-Vt., And Elizabeth Warren, D-Mass., And Buttigieg have jockeyed for position as they try to differentiate themselves as the best candidate to take on Trump.
Scroll down to see which candidates have clawed their way into the top five of national and early state polling averages in the field of 18. Other than Biden, Sanders, Warren and Buttigieg, only Sens. Kamala Harris, D-Calif., And Amy Klobuchar, D-Minn., Along with Rep. Tulsi Gabbard, D-Hawaii, have cracked the top five in a polling average.
The primary race got a bit more crowded this week, when former New York City Mayor Michael Bloomberg entered the fray. While he has decided not to focus on the first four nominating states, Bloomberg flooded several other important markets such as Texas, California and Pennsylvania with ads as part of a more than $ 30 million move.
The race can change again before the nominating contests start. Warren faced intense scrutiny, particularly of her health-care policy, after she enjoyed a polling surge in early October. Buttigieg could face similar focus from his rivals as he emerges as an early state threat.
