At least that is Fred Thompson's voting history according to a new article by David Brody at CBN:

"The most stark example was his 1995 vote on the welfare overhaul, when he voted to preserve illegal aliens' ability to receive federal benefits. He was one of just six senators to vote that way, joining four other Republicans and one Democrat. "

He also voted against an employment verification system:

"And in 1996, as Congress considered a crackdown on illegal aliens, Mr. Thompson voted against setting up a system so employers could verify the legal status of their workers. "

Fred has a lot of explaining to do. When compared to Romney, the differences are clear. Mitt ran for governor in 2002 opposing bilingual education, and then after winning, he implemented a program making sure all kids were educated in English. His record also includes:

Opposing driver's licenses for illegals
Vetoing instate tuition for illegals
Developing a program to have state police enforce immigration laws

Romney is the only major pro-enforcement candidate in the race. The record could not be more clear.
