The Republican Party is guilty of provoking government shutdowns as a regular tactic in the past 25 years, since the time when Newt Gingrich and the Republican Revolution came to power in the 1994 Midterm Elections under Bill Clinton.
It has undermined respect in our government, and hurt many people in the process, and it should never happen again.
Any attempt of any President to force a government shutdown should be opposed by both parties, ready to override a Presidential veto by a two thirds vote.
Since Federal Government workers are not permitted to strike, therefore the Congress has a responsibility to make it illegal to ever disrupt the nation as it has, due to Donald Trump, Mitch McConnell, and the Republican Party unwilling to keep their oath of office.
Effectively, they have been committing lawlessness, and hopefully, many will be wiped out of Congress in 2020.
