WHY, though?
It’s not like he’s ever going to be the President. Do I want to see YOUR tax returns? No.
Do you want to see MY tax returns? I certainly hope not.
I posted on another board that I thought it would be a great prank to put something on Trump’s teleprompter that is not what he’s supposed to be saying - gibberish, profanity, the latest Harry Potter book, etc.
Someone else replied, “How could you tell the difference?” 
“Go fuck yourself, San Diego!”
I was thinking this morning that the thing which would probably hurt Trump the most right now would be some scandal involving Pence.
There’s been talk about how Pence is the professional who’ll run things while Trump works on the big picture. Or how, worst case scenario, if Trump screws up real badly we can always impeach him and let Pence take over. Pence is like the safety blanket people are clinging to.
A significant scandal calling Pence’s abilities into question would remove one of the few remaining props that the Trump campaign has.
Didn’t his Indiana governorship call Pence’s abilities into question?
“Merely incompetent” looks pretty good next to Bankrupt Donny.
What, he can’t tie his shoes, make his own oatmeal? So what? He doesn’t have to!
Not to the people who are already supporting him. I’m talking about something new that would raise doubts. The Trump part of the ticket is already shaky; a blow to the Pence half would cause serious damage.
Reviving an old thread: Colin Powell’s hacked e-mails might count. He’s very respected, although certainly not flawless by any stretch of the imagination.
Instead of a baby…
At a rally, a handicapped person with a golden retriever helper dog with muddy feet, could be planted in the audience. It could be trained to run up and jump on Trump with its muddy feet, compelling Trump to kick the dog, and at the worst he would order his thugs to shoot the dog. Trump hates dogs.
