Donald Trump is sending a dizzying array of mixed messages — on a single issue all by itself.

• The president wants to build a “big, beautiful wall” along our southern border.
• He insisted again today that Mexico is going to pay for the wall; Mexico’s government has said it won’t do as the president insists.
• Democrats in Congress say that Trump’s insistence that Mexico pay for the wall takes Congress off the hook; there’s no need for Congress to worry about the money.
• Thus, we need not worry about a government shutdown, which Trump insists will happen if Congress doesn’t cough up $5 billion to pay for the wall that he insists Mexico will finance.

Are you as confused as I am? If so, then I don’t feel so badly.

I cannot keep up with Donald Trump’s messy mix of messages.
