A new PAC has been formed: Americans for Legal Immigration PAC:

Americans for Legal Immigration (ALI-PAC) has formed to address the disparity between the public's desire for more control of illegal immigration and the actions of lawmakers. Varied polls indicate that over 75% of America's legal citizens want more done to control illegal immigration, yet the elected officials who are willing to address this concern constitute a minority of members in the US Congress and Senate at this time. This must change.

Even more alarming is the disparity between our current laws and what is actually happening in the country. Illegal immigration is exactly as the title implies; it's illegal. If three fourths of America's legal citizens want illegal immigration curtailed and laws are in place to facilitate their wishes through a constitutional democracy, then why is America experiencing the largest population increase through illegal immigration in our history?

We are taking action and we need your support. ALI is dedicated to supporting candidates who make illegal immigration reduction a top priority. We are a nonpartisan political action committee and your contributions and membership will go to candidates that will work to reduce illegal immigration. We also plan to educate lawmakers, the media, and the public about the wishes of the vast majority of legal citizens to control illegal immigration and point out the negative impacts illegal immigration is having on our society...

Their founder appears to be a political consultant from North Carolina, but they don't seem to have any widely-known names involved. And, they've just started so their web site is a bit devoid of content. Nevertheless, hopefully they can move this issue forward.
