There was a time when Jim DeMint was committed to helping Sen. Marco Rubio achieve his goals.
At least not when it comes to remaking the nation's immigration laws.
DeMint is president of the conservative-leaning Heritage Foundation, which on Monday released a report contending that an immigration overhaul would cost U.S. taxpayers $6.3 trillion over 13 years in direct and indirect spending like welfare and public schools.
The immigration overhaul bill before the Senate would provide, among other things, more visas for migrant farm workers and high-tech workers, and a path to citizenship for the estimated 11 million undocumented immigrants in the United States.
One thing it would not provide is help for same-sex couples in which one partner is an American and one foreign-born. For heterosexual couples, a foreign-born spouse automatically qualifies for a green card and many of the benefits of citizenship. Not so with gay and lesbian couples.
