Depends on where they took this poll.
Don't underestimate the power of TDS. For instance... My aunt was a conservative all of her life. She moved from western North Dakota to just outside of Minneapolis, Minnesota way back in 1971, and over all these years maybe slid over to moderate conservative. But then something happened... As soon as it looked like Trump was going to win the nomination (his first term) she completely lost her fucking mind. Repeating verbatim what the media told her to believe about him. I can understand not liking the man. But she completely took a 180 on ALL of her core beliefs. It does not matter what it is, if it even remotely looks to be republican, she'll decry it vehemently. And the same is true of the other direction. If the dems claimed that all first born sons were to be sacrificed to Hillary Clinton, she'd argue until she was blue in the face how that would help society. She has completely distanced herself from any family that isn't a hardcore liberal. (remember, she's from western North Dakota, with her family having an oilfield/ranching background. Should tell you a lot) And that includes one of her own sons. Won't have a thing to do with him, his wife, OR their two children. Her own fucking grandchildren. Because of Donald Trump.
Oh, and a funny little side note... She moved from Anoka, Minnesota to Tennessee about 3-4 years ago. Because of the better taxes and less crime. But she's still voting to bring Minnesota policy into Tennessee.
