The American people are not going to believe that Trump is the reason for the border crisis. Bidens polling on that issue is in the toilet. People know who he’s been in charge the last three years.
What they could probably do and maybe get away with is saying that Republicans that opposed any compromise on the border was because they were afraid of Donald Trump and Trump force them to oppose it because he wanted the crisis so he could have an issue
That might work.
In that case, the American People really need to take a serious think on the meaning of "Compromise". In this case, as in many others, it means giving up something you want. The border security law is in place, a compromise means less.
Just enforce existing law, and this would not be an issue.
So the bottom line issue is that this Administration is NOT enforcing the law, as is its Constitutional Duty.
(It's high treason, folks).
