Plenty of people see it as the Democrats in Congress who are holding things up. (After all, there is universal agreement that border security is important. Also, many prominent Democrats have pledged support for physical barriers in the recent past.)

I tend to agree with Cher, which doesn't happen often. She says that Democrats can be seen as heroes if they compromise on the wall to re-open the government. (But if they do not do this, Cher believes the Democrats will ultimately suffer for the fallout.) Time may tell if she is right or not.
