So, Trump is maintaining this shutdown because he's unwilling to maintain the status quo on healthcare, using illegal and unconvincing messages on agency websites to try to blame it on the Democrats, and he just saw on Tuesday that his message is definitely not working. Like, super not working.
So, what does he hope to gain by continuing to pursue this angle? When you have headlines come out saying that a judge ordered Trump to fund SNAP and that Trump is ignoring and appealing that order, does he think that will somehow make him look good?
Trump's brain must be mush at this point.
