Which sport has the Trumpiest fans?

[7,052,770]

Hockey is an underrated answer, since the vast majority of their fans are white people from the suburbs.

The vast majority of hockey fans are Canadian, and therefore hate Trump.

The hockey heartland in the US - Alaska, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New York, North Dakota, Vermont - has almost 10 million more people than all of Canada. Also completely ignoring the fact that many prominent Canadian hockey personalities (who reflect the culture of many fans) like Bobby Orr and Don Cherry are as Trumpy as it gets.

You've obviously never met a hardcore Rangers, Bruins, or Pens fan. Or been to rural Minnesota or Michigan.

You forgot Rhode Island!
