Bedford, NH (LifeNews.com) -- Republican presidential candidate Tom Tancredo is a pro-life Colorado congressman best known for his views on illegal immigration. However, he tied the two issues together in a weekend speech to members of New Hampshire Right to Life -- who also heard representatives of Texas Rep. Ron Paul and former Gov. Mitt Romney.

Tancredo told the pro-life group on Sunday that his pro-life record goes back to his days in the Colorado state legislature where he was first elected in 1976. His state was the first to make abortions legal in 1967.

The congressman linked the pro-life cause with his crusade against illegal immigration and said that the tens of millions of abortions over the last few decades have contributed to a worker shortage.

Illegal immigration is fueled by that shortage, he said.

Ron Paul's son represented him at the pro-life forum and said the Texas congressman uses a Libertarian approach to the issue which opposes federal restrictions on abortions but advocates that states be allowed to make abortions illegal again.

He said Paul believes that other rights Americans enjoy are violated when the right to life is abrogated.

And a representative of Mitt Romney's campaign also attended and said the ex-Massachusetts governor is the strongest pro-life candidate seeking the GOP nomination.

Also this weekend, three more GOP candidates, Fred Thompson, Sam Brownback and Duncan Hunter, addressed Republican candidates forums in Wyoming, which has moved up its primary to January 5.

Brownback and Hunter touted their pro-life views extensively and said they would only appoint judicial candidates for the Supreme Court who understand Roe v. Wade was wrongly decided.
