Donald Trump’s most recent attacks consist mainly of calling Ted Cruz a liar – without any facts to back up that claim.*
Trump apparently has a double standard, but check out this article, originally published in USA Today on January 27, 2016:
I am not a Cruz fan, but I am very tired of Trump spewing insults and accusations against other candidates without any proof – and not being called on it by the mainstream media.
* Trump mentions the Cruz campaign tweets in Iowa about Dr. Ben Carson, which hinted Carson was dropping out of the race. While those tweets were not true, the fault most likely lies with Cruz aides, not Cruz. They may have lied or are just incompetent. (See my post on that event here.) Trump has not cited any other specific lies he thinks Cruz told.
