Obviously Trump wasn’t serious about delaying the election. What he was trying to do was bring attention to the crap going on regarding the mail-in voting scheme. Worked out well.
I suspect that Cruz’s problem is that he can’t comprehend Trump’s strategy, something he displayed earlier this week when he whined about Trump’s tweets (no different than my FDR-Democrat parents).
I guess nobody saw the question mark at the end of President Trump’s tweet. Changes the whole meaning. Then again, hatred blinds someone from seeing the obvious.
