Crowley Political Report

Donald Trump's ad attacking Jeb Bush is very short but brutal. In 15 seconds, Trump takes Bush's comment that for most immigrants coming to the United States "is an act of love," and juxtaposes Bush's remark with apparent pictures of convicted felons.

It is a huge distortion of Bush's beliefs about immigration. 

But it is also a hint at just how ugly this campaign for the Republican presidential nomination is going to get.
