Warnings made by Donald Trump and his Republican allies about the consequences of what will happen if democrats/progressives control American governments include the following:

• Accusations of taking the country backward:
• Claims about threats to democracy and American values:
• Allegations of enabling crime and chaos:
• Warnings about economic decline:
• Warnings about public broadcasting and media:

Because these warnings are quoted so often, there is good reason to assume that anyone — including President Trump — who uses this rhetoric actually fears democratic/progressive control of government. Moreover, President Trump has his own special reasons for fearing democrats: If both houses of Congress are controlled by democrats, they are likely to pursue impeachment proceedings against him.

These are all purely existential fears. No one — not even Democrats — know that what future will be for America — even regarding the impeachment issue. Nevertheless, Trump and Republicans use these fears to preserve their positions in government and mobilize voters who harbor a general distrust of government to reject Democrats in favor or Republican candidates.
