They definitely will. This will just be added to Trump's barrel of twitter gaffs and forgotten. I just hated to see all the momentum this week go to waste.
I've stopped thinking that Trump's choices were just him being unable to control himself.
Did you see the polling on the "squad" over the weekend? AOC has a HUGE amount of name recognition (73%) and only something like 17% had a positive impression of her.
One of the others (Talib, I believe) had only a 53% name recognition, and a NINE% (I spelled it out because it's so abysmal) positive impression.
He's raising their profile and, yes, stopping the infighting, because he wants THEM to be the face of the Democrats.
It's possible this is all just by chance, but it works out in his favor far too often for me to believe that, anymore.
