One of the biggest myths about government shutdowns is that presidents usually win.
This may explain why President Donald Trump threatened to continue the shutdown for months, even years. However, a poll conducted in the first week of January shows that 51% of adults believe Trump is to blame for the shutdown.
There have been 18 shutdowns since 1977. I found that in the nine longest shutdowns during that time, presidents lose an average of 3 percentage points of public support or approval during a government shutdown of four or more days.
