Liberals know they're losing the demographic war. Christians have lots of children and adopt lots of children; liberals abort children and encourage the gay lifestyle in anyone with a flair for color.
They can't keep up.
Population expert Nick Eberstadt recently speculated in The Washington Post that a principal reason for America's high fertility rate compared to Europe's is its religiosity. Well, that leaves liberals out.
The Democratic Party is in the fight of its life against a conservative demographic trend. Its only hope is to gerrymander America to make the poorest half of Mexico a state. Only a massive influx of criminals, wards of the state and rioters can save them.
This is why Democrats are obsessed with giving two groups the right to vote: illegal aliens and felons. With Arellano, they get two for the price of one. To liberals, building a wall across the Mexican border is a violation of the Voting Rights Act.
