Here's a couple from the Daily Beast.
[On the night of his Indiana win] The fun and games were finally over for Trump, and he knew it.
No longer the insurgent outsider, he’s now faced with a choice. He can continue to be himself, peddling conspiracy theories and insulting every foe with the sophistication of a preteen mean girl. Or he can start acting like a statesman and risk losing the people who love him the way he is.
Indeed, what will he do now? And what will he do when his past comes back to haunt him?
Trump's haunted house: Will the ghosts do him in?
And what will he do to spin his way out of his retched past? Draft dodging, sleeping around, yuuuuge list of insults to minorities (who maybe he does not need to win) and women (who he clearly does need). All that is a Christmas basket of oppo research. Consider just the theme of Trump's treatment of vets.
When Trump had his chance to join the military and fight in Vietnam, he did not take it. Instead, the rich kid got multiple student deferments from the draft and a medical deferment. Meanwhile, men like John McCain were being tortured as prisoners of war, but Trump has said that is dishonorable.
Since running for office, Trump has made a show of fundraising for veterans—offering veterans groups six-figures to be props at campaign rallies. But when vets groups have stood up to him, refusing to be dragged into the campaign, scores of Trump fans have sent them vile and harassing messages.
It’s in line with how Trump treated veterans before he started running for president.
In the 1980s, Trump tried to have disabled veteran street vendors thrown off Fifth Avenue, accusing the Vietnam-era soldiers of ruining how the street in front of Trump Tower looked. Before his presidential campaign, Trump’s charitable foundation gave more to the Clintons than to veterans organizations.
Donald Trump will make veterans great again? Donald Trump: The veterans president? He's not off to a good start.
It's all out there. Now all the Dems have to do is pick it up and play hard ball with it. They can start by Googling "Trump quotes." It's a gold mine out there! Here are examples from the International Business Times and the Financial Express. He doesn't stop with women, minorities, and vets; he bashes nations too.
