Most immigration ads from Republican presidential candidates focus on border security and little else. Think "build the danged fence" from John McCain in 2008.

A new ad from Ted Cruz, though, takes a different tack — and does so in a matter that is sure to grab attention.

The ad features men and women in business attire — think suits and ties, dress shoes — streaming across the border. It features Cruz asking whether the immigration debate would be the same if white-collar professionals like lawyers, bankers and journalists were coming across the border, taking these Americans' jobs and depressing wages.

The very populist implication, of course, is that the border isn't secure because it isn't in the interest of more well-off Americans — and that Americans who are struggling economically are paying the price.

If nothing else, the image of people in suits running through the Rio Grande should capture people's attention.

The campaign for Republican presidential candidate Ted Cruz released an ad envisioning a different kind of immigration crisis on Jan. 5. (Ted Cruz)
