GOP voters are confused about Rudy Giuliani

Rudy Giuliani continues to enjoy a wide lead over his rivals for the Republican nomination for president in part because a large majority of GOP voters still don't know the former New York City mayor favors legalized abortion.

Newsweek found that Giuliani won in hypothetical head-to-head matchups against both Sen. John McCain and former Gov. Mitt Romney. However, only one third of Republicans who say they are social conservatives knew Giuliani is pro-abortion.

The Democratic ticket is more clear on this issue, with most Dem candidate supporting abortion rights. Barack Obama has been fighting for a woman's right to choose for over a decade.
