An article that is far too long for the liberal mind to grapple with, so I advice the RJ libs to not click the link to read the full article.

There’s no mystery about why Democrats resist enforcing our immigration laws. A new “sanctuary cities” map from the Center for Immigration Studies goes a long way toward explaining why open-borders Democrats are so addicted to flouting our immigration laws. When you consider the political makeup of the cities, counties, and states where illegal aliens are welcomed, you start to suspect that the liberal elite in San Francisco and elsewhere aren’t interested only in cheap nannies and gardeners. For them, pulling in more illegal aliens is, perhaps first and foremost, about pumping up their political power.

A bit more:

Data from the Migration Policy Institute show that 3.2 million of the nation’s 11 million illegal aliens reside in just 19 counties that include the sanctuary cities of the deep-blue states listed in the previous paragraph. Furthermore, because these estimates are based on Census Bureau mail-in forms, which some commentators believe illegal aliens are on average less willing to return, they likely undercount the true level of illegal aliens in these counties.
