You are confusing apples and oranges.
Trump did not attack Cruz’s father by referencing a photo and an article that said he had been seen in the company of Lee Harvey Oswald just before the assassination.
Nor did he attack Cruz’s wife by re-tweeting an unflattering comparison photo of the wives. Despite the attacks on Melania Trump apologized for re-tweeting the photo saying he was angry but he should not have re-tweeted. Ms Cruz inserted herself into the campaign saying that she & Ted were running so her globalism history & Goldman Saks connections were fair game.
Has Cruz appologized for the personal attacks on Melania Trump made on TV by his surrogate on March 8th or by the photos posted by the Cruz Pac a week later, or the fliers passed out by his campaign office suggesting Mrs Trump’s modeling career left he soiled and unfit?
Wow, looks like quite the hornet’s nest strike here!
