I used to work for a media company that covers the stock/trading markets. They've asked me to write a few guest columns leading into the election.

I'd like to write one for Monday that really hammers Trump. What topic/theme/argument would be both (a) harmful to Trump (b) likely to spread virally on social media (assume I am a competent writer) and would (c) have an impact on either undecided voters, weak Trump supporters, or boost anti-Trump turnout.

Please and thank you.
