Trump was relentless in his attacks against Cruz while he made very little effort during that same time period to go after the DEMS. Trump attacking Cruz's wife and father was despicable, unwarranted, bombastic and absolutely not presidential.
Trump has insulted entire groups of people and individuals; women, blacks, Hispanics, disabled, veterans, Megyn Kelly, Mitt Romney, Susana Martinez, Joe Biden, Corey Booker, John Allen, Judge Curiel, Nikki Haley, John McCain, Rick Scott, Eric Erickson, Hugh Hewitt, etc., etc. Most recently; Trump criticized "Joe" co-host Mika Brzezinski in highly personal terms, calling her "off the wall, a neurotic and not very bright mess!" He also implied that Brzezinski and Joe Scarborough have been secretly dating. He called them "two clowns."
The only clown is the orange baboon who is also a narcissistic psychopath!
