Washington, DC (LifeNews.com) -- Congressman Ron Paul told activists at the Conservative Political Action Conference on Thursday that he's the only authentic pro-life conservative left in the race for the Republican nomination. He talked about legislation he's put forward on abortion to authenticate his position.

Though John McCain has sewn up more than half of the delegates necessary to secure the Republican presidential nomination, Paul isn't ready to give up.

In fact, he took a shot at the Arizona senator saying he can't restore conservative principles.

“If you think we can lead this country back to conservative principles… you have another thing coming, because it’s not going to happen,’’ Paul said

He said that at least 42 delegates to the national convention belong to him and he plans to continue making his case for his principles.

Paul said Republicans should turn to him to restore GOP control over Congress.

"We have lost House seats," Paul said yesterday, "Not because we aren't compassionate, but because we aren't conservative."

Paul backed up his claim by pointing to pro-life legislation he's introduced in Congress.

He said he's proposed a "sanctity of human life" bill that would establish the principle that human life begins at conception.

"That's not a political statement, that's a scientific statement," he said.

Paul also touted a bill of his that would prevent the federal judiciary from having any authority over the abortion issue.

"Such legislation would allow states to have greater latitude in setting policy as it pertains to abortion without judicial legislation," he explained.
