In today's WSJ, Richard Nadler has a column (based on his "Border Wars" report) claiming that the GOP will suffer electorally for any seeming opposition to "comprehensive immigration reform." Nadler is the president of Americas Majority, a pro-"conservative" group. This group is now advocating in favor of "comprehensive reform," but with some interesting twists. It seems to be quite openly in favor of "amnesty" (something many supporters of the "grand bargain" said they were against). And it's on the verge of a scorched-earth campaign against opponents of "comprehensive" reform.
For example, in an ad against punishing employers for the hiring of the "undocumented," a voice asks:

Listening to the anti-employer rants on talk radio these days, I wonder: Is it illegality that the anti-immigrant crowd hates? Or is it really free enterprise?

Implication that supporters of enforcing employment laws are closet socialists? Check.
The "Economist" ad also pushes the claim that some are "smuggling Communist theories into the discourse of the political Right."
