According to Peter Wallsten of the Los Angeles Times, unspecified immigration groups will be making a push for comprehensive immigration reform this fall that would see the Democrats try to get it on their own without bringing business interests into their big, crooked tent: link (See also last month's "Hilda Solis to prefer labor enforcement to immigration enforcement?")

Under their scheme, there'd be a massive amnesty, following by:

an independent commission that would assess labor and industry data to decide how many foreign workers should be allowed into the country. The system, designed by Ray Marshall, a Labor secretary under President Carter, would replace a maze of special temporary worker visas that are granted each year to high-tech specialists, agriculture workers and other foreigners brought into the U.S. by foreign and domestic firms.

That would probably alienate business groups like the US Chamber of Commerce, but the thinking is that it would bring the AFL CIO on board.

And:

To bolster their cause, advocates are planning an $18-million media and grass-roots campaign for the fall. The funding is coming primarily from liberal foundations, including one founded by billionaire activist George Soros.

Since there are several of those it's difficult to know which it could be.
