Well, if you say something long enough, people begin to believe it. Example- Trump.
By that same logic, a lot of people have now started coming out with real attacks on Trump and the people will listen. Here are some facts that have so far been revealed and they'll keep repeating these like a marketing message:
1.
Trump the Rapist: Trump has had his fair run of sexual/misogyny related law suits. So far, no one took him seriously enough.
Case 1
Case 2
. There are plenty of other cases like this and the women involved may have settled back then but they still stand by the fact that he did what they had alleged he did.
2.
Trump the Cheat: Trump has had multiple lawsuits, which he lost, where people alleged he had cheated them out of money. I was myself cheated by his "Trump University" which was nothing but a sham. There are infact 169 such cases that they've found so far. And its politics, he is going to have to answer for each one of the cases, including the handful of cases where he himself sued someone and still lost.

3.
Trump the non-christian: We know what the Pope said. And this matters to a lot of GOP voters. But, there's more. Check out his speeches from the past at Liberty University and you'll know that this is not a facade, he is crazy, he is xenophobic, and he is saying nothing new.

And let's not forget about the Birther Issue:
Birther Issue
, which actually made him the butt of a zillion jokes and for the first time made a lot of people realize how fickle the man really was.
Also, like John Oliver said, Trump's not even a Billionaire and he's not the "success" that he projects himself to be.
Now that they've started pulling out dirt on him, he's going to have a tough time.
