Thursday night on "The Colbert Report," host Stephen Colbert discussed the fact that Republicans are having a hard time scoring new voters among the changing demographics of the U.S.. The mostly white conservative party's hard line on immigration and social programs have made it hard to recruit among non-whites, who feel that the Republican Party is against them, one of the consequences of -- as Bill Clinton told Jon Stewart -- being a party that allows ideology to override the evidence.

In the words of Sen. Lindsey Graham (R-SC), "In the demographics race, we're losing badly. We're not generating enough angry white guys to stay in business for the long term."

One way of changing that, said Colbert, would be for Republicans to mail-order his "Stephen Colbert's Formula 401: Seeds of Discontent" angry white guy sperm.

"Harvested," he said, "from my grapes of wrath."

"With a dwindling supply of white Republicans, the GOP has got to reach out," he continued, hence former Gov. Mitt Romney (R-MA)'s decision to appear on Tuesday night in an interview with the Spanish language network Univision in an effort to shore up his support among Latino voters.

Unfortunately things didn't go so well for Romney. A bad spray-tan or TV makeup job resulted in his looking several shades darker than normal, an error that some have chalked up to the candidate's desire to fit in with Latino voters by way of wearing "brown-face."

During the interview, Romney slipped up and used the phrase "illegal aliens" to describe people affected by the DREAM Act, a term that is considered a slur by many.

Colbert pointed to Romney's invocation of "self-deportation" during the Republican primaries, where the candidate said that rather than go to the trouble to round up and deport undocumented immigrants, under his administration, the government would make life so difficult for undocumented workers that they'd have no choice but to "self-deport" and return to their homelands.

"Much in the same way that conservatives are 'self-deporting' from the Romney campaign," Colbert said referring to recent stiff criticisms of the candidate by Bill Kristol, Peggy Noonan, David Brooks and others.
