A week after Christian Coalition founder Pat Robertson's endorsement of Rudy Giuliani, the National Right To Life committee is endorsing Fred Thompson.

The pro-life organization calls Thompson the Republican most likely to beat Giuliani, who's pro-choice.Officials with the right to life call the endorsement important because it represents 3-thousand chapters across America, rather than just the view of one person.Thompson's campaign hopes this endorsement helps him in Iowa, where religious Republican voters are very important.

Thompson is currently running fourth in Iowa among Republicans and some are still questioning his passion for the presidency.That was the question by an NBC reporter traveling with Thompson through Iowa.

As many of the Republican candidates run against each other, It appears Rudy Giuliani is running against just one person, Hillary Clinton. The issue again this week is driver's licenses for illegals. During a campaign stop, Giuliani said he was glad New York governor, Eliot Spitzer had dropped the plan to let illegal immigrants get driver's licenses.

Hillary Clinton in a debate earlier this month did not directly answer whether she supported Spitzer's plan. Political observers say Giuliani's comments were directed more at Hillary than New York's governor.

And while Giuliani accuses Clinton of dodging questions, it was revealed this week that her campaign helped stage some questions during a town hall meeting in Iowa.

Clinton's campaign admitted that they planted people on two occasions in the audience to ask her easy questions. Clinton has since apologized for those incidents and said the debate needs to focus on who can best enact the change that all Democrats are talking about. While Clinton is leading other Democrats in national surveys, polls in Iowa have tightened. Both Barack Obama and John Edwards say it's time for a change that Clinton can't produce.

Meanwhile, Edwards is launching a new ad in Iowa this week promoting a health care idea. He says he'll end health benefits for top politicians who don't approve a universal health care plan within 6-months after he takes office.

Mike Hukabee has not been considered a top-tier candidates, but that is no longer the case, at least in Iowa. Once viewed as a long-shot to win the GOP presidential nomination. Mike Huckabee is making headway in the Hawkeye state. In a New York Times/CBS news poll, Huckabee is the second choice among Republicans in Iowa. Iowa front-runner Mitt Romney received 27-percent of the vote with Huckabee getting 21-percent.
