One of the mems of the left is that America is not welcoming for illegals and others. They claim that we do too much to stop terrorists, criminals, and illegals from entering the U.S. Groups like American Society of Travel Agents and the National Association of Realtors are a lobby for easing any restrictions on issuing visas or stopping illegals at Ports-of-Entry. They just want as many 9/11 hijackers here as possible in hopes to sell airline tickets and real estate to them.
And Baraka Hussein Obama is their ally. While lobbying for the Chicago bid for the Olympics, Obama basically promised to stop enforcing immigration law at the borders in order to "welcome" people from around the world. http://www.weaselzippers.net/blog/2009/10/yet-again-obama-used-his-plea-to-ioc-to-bash-america.html (h/t Weasel Zippers http://www.weaselzippers.net/blog/)
We also encountered this during the Atlanta Games when the late unlameted INS ordered its inspectors to go easy on anyone claiming to be coming for the games. They wanted visitors to feel welcome and not to be questioned closely in any manner. Of course what happened was that thousands of Mexicans and other came here claiming to be coming for the games, but in reality coming to live here illegally.
What we can expect even without the games if the the Obama Regime to stop enforcement of our immigration laws at the border in anticipation of the upcoming amnesty.
