This kind of ad can easily backfire. While it will probably help solidify some of the minority vote (which wasn't likely to leave her anyway), it's very distasteful and could alienate a lot of independents because it's so obviously disingenuous. While I vehemently disagree with most of Trump's policies, I don't think people who want to control the border are necessarily racists or white supremacists, although some will be. This is the kind of smearing they initiated against Ron Paul (whose immigration policies I also disagreed with).
These guys are scarier than BLM, John McCain, Bolton, Soros, the Fed? Think of Blazing Saddles. http://www.snopes.com/clinton-byrd-photo-klan/
What's funny is the ad that played before the video was for Lockheed Martin, a company that has helped initiate wars, shaped US foreign policy, and caused massive destruction across the ME and the rest of the world (and made Americans less safe). I assume they want Hillary for president (I used to think Trump would be better on foreign policy, but with all the posts from Mr. Wenzel, I'm not sure anymore): http://www.corpwatch.org/article.php?id=14307
