At this point, opponents of Trump don't even have to make the case. His very own party is burying him. This is from Ronald Reagan's political director, a life long conservative Republican:

Trump falls short in terms of the character and behavior needed to perform as president. This defect is crippling and ensures he would fail in office. Trump is a bigot, a bully, and devoid of grace or magnanimity. His thin-skinned belligerence toward every challenge, rebuke, or criticism would promise the nation a series of a high-voltage quarrels. His casual dishonesty, his policy laziness, and his lack of self-awareness would mean four years of a careening pin-ball journey that would ricochet from missteps to crisis to misunderstandings to clarifications to retractions.
Of course you probably heard 50 other Republicans also signed a a form stating Trump would put the country at risk:

You have several Republican senators openly saying they will now vote for Hilary Clinton because they cannot in good conscience vote for Trump, and these are people who hate Clinton:

Then you have previous Republican nominee for president, Mitt Romney rebuke Trump and state he will not vote for Trump.

You have the amazing thing no living Republican president (not Bush I or II) willing to endorse Trump.
Ronald Reagan's son shreds Trump, calls him a scam-artist:

His own party are turning against him, and these people have no love for Hilary Clinton, and I'd bet a number of high ranking Republicans are biting their tounge right now, if Trump does not gain ground in the polls soon, there will be an open revolt in the Republican party as people scramble to diassociate themselves from Trump's sinking Titanic of a campaign.
