Colorado congressman and possible GOP presidential candidate Tom Tancredo is making an effort to inform potential supporters about how he feels on other areas besides illegal immigration, which has been his bedrock issue.

Tom Tancredo has formed a presidential exploratory committee as he considers making a bid for the Republican nomination. The Colorado Republican is aware that some consider him a "one-issue candidate" — that being immigration. He understands the limitations of such a label.

"You cannot run for president on a single issue," he admits. "[But immigration] is the issue that propels me — and it has [multiple] facets," he continues. "It’s amazing how many things are connected to the issue of immigration."

The lawmaker says he wants people to know how he feels on a wide spectrum of concerns — and that immigration is not a single issue. "It touches our educational system, our medical system, our national security, our culture," he shares. And that culture, he says, is under attack.

"We are risking the development of a bilingual nation and a multicultural nation, which is almost an oxymoron," Tancredo suggests. "It is very difficult to maintain something like that, especially [under] the kind of threat situation we’re in today with fundamentalist Islam."
