At the GOP Debate in Simi Valley, California, Republican candidates all move their stances on immigration further right.

After a big win in Florida on Tuesday, John McCain seemed on top of his throne at the CNN/Politico debate. He and Mitt Romney dominated most of the discussion where Romney was forced to explain his government mandated universal health care plan he implemented as Governor of Massachusetts while McCain tried to convince he was strong on the economy.

But immigration, a hotly contested issue in Southern California received much attention. And all candidates attempted to show their conservative credentials through an anti-immigration agenda.

First Mike Huckabee, the former Arkansas Governor who supported the DREAM Act, allowing undocumented youth in-state college tuition, now says the southern border wall can be built with haste.

"First making sure that the fence is built with in 18 months and second that we have a process that the people are here go to the back of the line and start over." Huckabee says.

Mitt Romney the former Governor of Massachusetts now says many undocumented people can be deported with in 90 days.

"How do people return home? Those who came here recently, you have to go back home with in 90 days. For those who have kids in school, you let the kids complete the school year then they go home. For those who have been here a long time with kids that have responsibilities here and so forth, you let stay long enough to organize their affairs and then go home."

And Arizona Senator John McCain says he would not vote for the comprehensive immigration legislation he wrote with Senator Ted Kennedy. He has recently adopted a secure border first approach.

"We know what the situation is today, that people want the borders secured first."

Ron Paul was at the debate and supports a secure border.

Representative Ron Paul of Texas was at the debate. He did not address immigration but supports a technology-based border fence.
