More like petty, small and vindictive.
Trump has shown himself to be the king of pery small and vindictive. HE is a malignant narcissist like Obama and his pedopho;e pas BJ Clinton.
Je committed "blood Libel" against Cruz his wife and is family, he owes Trump zero when Trumo committed Blood Libel against Cruz there was no more pledge. Trump had a obligation to behave is a reasonable manner, he didn't. Trump wants to have his cake and eat it too, sorry life doesn't work that way.
"The term 'blood libel' can also refer to any unpleasant and damaging false accusation, and has taken on a broader metaphorical meaning"
