According to a poll conducted by YouGov on behalf of the Cato Institute, almost 2/3 of Americans are afraid of sharing their political views. And with some reason, it seems: among strong ‘liberals’, 50% would support firing a business executive who had privately donated to the Trump campaign. Among strong conservatives, 36% would support firing an executive who donated to Biden. Even among those who identify as just ‘liberal’ rather than ‘very liberal’, 43% would be in favor of firing a Trump donator…22% of conservatives would be in favor of firing a Biden donor.
