Democrats are incapable of thinking very far ahead. Just stomp on the rights of the law abiding and make it look like you are concerned or throw 22 trillion at a problem.
How many trillions have the Republicans thrown at their War on Terrorism? How did that work out for you?
America's biggest terrorist threat is white guys with guns who run amok in churches, schools, shopping malls, and movie theatres. You want to deport all Muslims as a threat to security but there have been more attacks by white guys with guns than by Muslims.
Sadly, no matter how many mass shootings by white guys with guns that occur, Americans never suggest that unrestricted gun ownership might be a problem.
Your solution to school shootings is to arm teachers.
