Buttigieg's campaign made a decision in the past few months to move toward the center. He has, for example, been clear in his attacks on Warren and "Medicare for All." Caucusgoers seem to be picking up on this shift.
Take a look at where Buttigieg is scoring among different ideological groups. He's at 12% among those who say they are very liberal, 25% among those who identify as liberal and 30% among moderates and conservatives.
This pattern simply didn't exist in our September poll. Buttigieg was at 7% among very liberals, 14% among liberals who aren't very liberal and 8% among moderates and conservatives.
Back in June, Buttigieg's weakest group was moderates and conservatives. He earned 18% who are very liberal and liberals who aren't very liberal. He was at only 10% among moderates and conservatives.
In other words, Buttigieg's actually doing worse with very liberal caucusgoers than he was in June, even as he is doing considerably better among caucusgoers overall.
Today, 63% of likely caucusgoers believe Buttigieg's ideology is "about right". That's the highest of any candidate tested. A mere 7% believe he's too liberal, while 13% think he's too conservative.
Buttigieg seems to be taking advantage of a rising number of caucusgoers who think Warren is too far left. Now, 38% believe she is too liberal, which is up from 23% in March. That could be deadly for her campaign if voters think her leftward tilt hurts her electability.
But perhaps the candidate most harmed by this Buttigieg's tack to the center is Biden. Biden's down from 31% among moderate and conservatives in September and June to 20% now.
