Here are a few more anti-immigration quotes from liberals who have since sold out.
Glenn Greenwald, November 2005
The parade of evils caused by illegal immigration is widely known, and it gets worse every day. In short, illegal immigration wreaks havoc economically, socially, and culturally; makes a mockery of the rule of law; and is disgraceful just on basic fairness grounds alone. Few people dispute this, and yet nothing is done.
Paul Krugman, March 2006
[I]mmigration reduces the wages of domestic workers who compete with immigrants. That’s just supply and demand: We’re talking about large increases in the number of low-skill workers relative to other inputs into production, so it’s inevitable that this means a fall in wages. […] the fiscal burden of low-wage immigrants is also pretty clear.
Paul Krugman, March 2006
Realistically, we’ll need to reduce the inflow of low-skill immigrants. Mainly that means better controls on illegal immigration.
Democrat Party’s 2008 platform
We cannot continue to allow people to enter the United States undetected, undocumented, and unchecked. The American people are a welcoming and generous people, but those who enter our country’s borders illegally, and those who employ them, disrespect the rule of the law.
