Dramatic in the results of the tracking poll was the swing among the top four candidates since it was last conducted in September, with Sanders up 13 points and Buttigieg up 11 points, while Warren and Biden dropped 6 and 10 points respectively. Biden leads with 24 percent, while Buttigieg, who has been rising this month, got 16 percent.
The survey also found that Medicare for All, a proposal touted by both Sanders and Warren, is growing "increasingly unpopular among all American voters", which could explain Buttigieg's ability to catch up to them in the polls. Among moderate/conservative voters, Buttigieg leads with 23% support, followed by Biden with 18%, Sanders with 17% and Gabbard with 11%.
The poll also comes as Buttigieg enjoys a surge in early state polls and on the heels of three consecutive Iowa surveys showing the Indiana Democrat leading in the Hawkeye State's caucus, while another New Hampshire poll shows him edging out the competition in that state's primary.
Buttigieg still remains in fourth place in the national poll aggregate compiled by RealClearPolitics, behind Biden, Sanders and Warren.
The poll carried an overall margin of error of 3.2 percentage points and included 574 Democratic voters and independent voters who lean Democratic. "Buttigieg has broken into the top tier, apparently at the expense of Warren, who has taken a dive after being hammered for being too far left on health care and other issues", Quinnipiac University polling analyst Tim Malloy said in the survey report.
A Quinnipiac University Poll released Tuesday says not only did his approval rating rise a couple of points, but support for impeaching and removing him from office is down. After steady momentum over recent months, the new poll shows her slumping from 28 percent in October to 14 percent. And in a sign the field could rejigger further, 55 percent of Democratic primary voters said there's a chance they could change their minds ahead of the February 11 primary.
