"Are you not aware of his corrupt and checkered past where he has been know for decades as a cheat, a fraud, and a disgraceful person --- he has been involved in over 3,500 lawsuits.... think about that."

How would you respond to this?

I quick google search says: Of the 3,500 suits, Trump or one of his companies were plaintiffs in 1,900; defendants in 1,450; and bankruptcy, third party, or other in 150. Trump was named in at least 169 suits in federal court.
