Rick Santorum Drops Out: Here Are The Worst Moments From His Presidential Campaign (VIDEO)

It's incredible he made it this far.

Ever since Rick Santorum declared his candidacy for the Republican presidential nomination last June, the former senator from Pennsylvania has been on the far-right edge of nearly every social issue, from reproductive rights and marriage equality to global warming, education and welfare.

On the campaign trail, Santorum showed little desire to appeal to moderate Republicans. Some of his most shocking moments were when he said he didn't want to make "black people's lives better" by giving them "somebody else's money," or when he told CNN's Piers Morgan that a woman who had been raped should "make the best out of a bad situation." Then there's the time when he called Barack Obama a "snob" because the president said he wanted all Americans to go to college.

We've compiled the most striking moments from Santorum's presidential campaign. Click the video above to watch.
