Republican mega-donors asked their employees who they will vote for in survey

Staunchly pro-Trump Uihleins gave anonymous survey to workers at Uline, headquartered in swing state of Wisconsin

The Republican mega-donors Dick and Liz Uihlein, who are the third largest donors in this year's US presidential election, have sought information about who employees at their company Uline will be voting for in Tuesday's ballot.

A screenshot seen by the Guardian shows how employees at the private Wisconsin paper and office products distributor were asked to take part in what was called an anonymous survey to track who the employees were voting for on 5 November.
