President Donald Trump keeps slamming Amazon as a part of his attacks on The Washington Post — but a Wednesday poll from the left-leaning firm Public Policy Polling found that his supporters overwhelmingly like the company.

The poll found that 53% of respondents who voted for Trump had a favorable view of Amazon, while just 20% held an unfavorable view of the company. Another 27% said they were not sure.

Among all respondents, 60% held favorable views of Amazon, while 13% viewed the company unfavorably and 26% were unsure.

Trump has been ramping up his attacks against Amazon in recent weeks. During his Tuesday-night campaign rally in Phoenix, Trump called The Post "a lobbying tool for Amazon." The Post is owned by Amazon founder and CEO Jeff Bezos.

Last week, Trump tweeted that Amazon was "doing great damage to tax paying retailers."

"Towns, cities and states throughout the U.S. are being hurt — many jobs being lost!" he wrote.

He's repeatedly tweeted about the "Amazon Washington Post" and the "AmazonWashingtonPost" while blasting coverage in the publication.

"The #AmazonWashingtonPost, sometimes referred to as the guardian of Amazon not paying internet taxes (which they should) is FAKE NEWS!" he tweeted in late June.

Public Policy Polling surveyed 887 registered voters from Friday to Monday. The margin of error was 3.3 percentage points.
