Ted Cruz didn't win Iowa, he stole it. That is why all of the polls were so wrong and why he got far more votes than anticipated. Bad!— Donald J. Trump (@realDonaldTrump) February 3, 2016
Trump criticized the Texas senator for spreading rumors that neurosurgeon Ben Carson was dropping out of the Iowa caucuses. A day after winning the Iowa caucuses, Cruz Tuesday issued an apology to Carson after his staff falsely told Iowa caucusgoers that Carson planned to quit the race, calling it a "mistake."
During primetime of the Iowa Caucus, Cruz put out a release that @RealBenCarson was quitting the race, and to caucus (or vote) for Cruz.— Donald J. Trump (@realDonaldTrump) February 3, 2016
Many people voted for Cruz over Carson because of this Cruz fraud. Also, Cruz sent out a VOTER VIOLATION certificate to thousands of voters.— Donald J. Trump (@realDonaldTrump) February 3, 2016
Trump is doing more than just going after Cruz on Twitter; he's doing it in his campaign speeches and at his news conferences. When ABC News asked Trump at a news conference Tuesday night whether Cruz is running a dirty campaign, he said, "I think he was certainly dirty. What he did to Ben Carson was terrible. I think what he did to voter violation forum; I thought that was terrible."
