Provoking fear in order to get someone to get stuff done. What Republicans use to fight terrorism and what Democrats use to fight global warming or climate change or whatever they're calling it now.

The Republicans are fearmongering so much that Americans are actually starting to believe another attack is coming soon.
The Democrats are fearmongering with global warming to the point where people have just stopped driving their cars altogether.
