Here are the polling averages heading into today’s Illinois GOP Presidential Primary.

Mitt Romney leads by double-digits, and looks poised to win. But, he looked ready to win in Mississippi last week. Santorum has frequently outperformed his poll numbers. Illinois will be a tougher place to do so. We’ll see how it turns out.

Two new polls in Illinois give Mitt Romney a lead over Rick Santorum in the GOP Primary to be held Tuesday, March 20.

We Ask America puts Romney up by 6-points, 37%-31% over Santorum. Rasmussen has Romney up by a larger margin of 9-points, 41%-32%. Our Average of Polls for Illinois has Romney leading Santorum by 6.4 points.

But is has to be remembered how wrong the polls were in Mississippi this past week, where Rick Santorum won despite trailing by at least five points in all the polls. Santorum has consistently outperformed his poll numbers throughout this campaign.

The 7-Day Polling Averages for the Alabama and Mississippi Primaries, to be held today, March 13, 2012, show a very close race shaping up. You can click on the state names above to see the actual polling data. If Romney wins in either of these Southern States, it will fuel his already growing momentum. If Gingrich wins one or both states, it will give him legitimacy to stay in the race. Santorum has to be hoping he can pull out wins in both states to force Gingrich out of the race, giving him a chance at Romney one-on-one the rest of the way.

Two new polls show both Mitt Romney and Newt Gingrich surging in Tennessee, just one day before the Tennessee GOP Presidential Primary.

Rick Santorum still leads – but barely. He had enjoyed a 10-20 point lead just a week ago. He now leads in our 3-Day Average of Polls by 2.6 points.

A new Public Policy Polling (PPP) survey gives Santorum a five-point lead over Mitt Romney, 34%-29%, with Newt Gingrich surging up to 27%, within striking distance.

A We Ask America Poll just released makes it a virtual 3-way tie in Tennessee: Santorum 30%, Romney 29%, Gingrich 29%. A Romney victory in Tennessee would be huge for him, showing he can win in the South. But a victory for Newt Gingrich to go along with a win in Georgia would enable him to stay in the race and claim he can be a viable alternative to Romney. Right now, it’s just too close to call, but Gingrich certainly appears to have the biggest surge going on in Tennessee.

Check out all the latest poll averages for the “Super Tuesday” States, March 6.

Heading into today’s Washington GOP Caucuses, two polls give Gov. Mitt Romney the edge.

A recent Public Policy Polling survey gives Romney the momentum, and a 5-point lead over Rick Santorum, 37%-32%. But a Survey USA Poll just out gives Romney a larger 14-point advantage over Santorum, 38%-24%.

The outcome today in Washington should give the winner some positive buzz heading into “Super Tuesday,” March 6, when 10 States will hold Primaries and Caucuses. A total of 43 delegates are up for grabs in Washington.

UPDATED 2/28/12, 7:45 AM ET: Two other polls done yesterday have been released, and they give Mitt Romney a one and two-point edge over Rick Santorum. That has moved the 3-Day Polling Average in Michigan to a 0.8 point lead for Romney – in other words, it’s a virtual tie.

To make it more complicated, Public Policy Polling reports that Romney holds a strong edge in absentee votes already cast, while Santorum is polling strong among those who are planning to actually cast their vote today. An additional unknown factor is how many “Independents” and Democrats will turn out and vote for Santorum as a way of stopping Mitt Romney. Some on the Left are advocating that, believing Santorum to be the weaker opponent to Barack Obama. Santorum has been making a big pitch to Democrats, seeking to take advantage of that possibility.

The big question is whether the turnout for Santorum today will be large enough to overcome Romney’s big advantage with absentee voters. Santorum seems to have the momentum. If he pulls it out, it will be a devastating blow to Romney on what he has called his own home turf. It’s going to be close.

Public Policy Polling is out with their final poll on the GOP Presidential race in Michigan, and it shows closing momentum for Rick Santorum:

PPP: PPP’s final poll in Michigan finds Rick Santorum holding on to the smallest of leads with 38% to 37% for Mitt Romney, 14% for Ron Paul, and 9% for Newt Gingrich.

It’s always good to be cautious with one night poll numbers, but momentum seems to be swinging in Santorum’s direction. Romney led with those interviewed on Sunday, but Santorum has a 39-34 advantage with folks polled on Monday. The best sign that things have gone back toward Santorum might be that with those polled today who hadn’t already voted, Santorum’s advantage was 41-31. . . . Read More

We added the polling for Monday that had Santorum leading 39%-34%, and it results in a tie right now between Santorum and Romney in our 3-Day Average of Polls, 36.3%-36.3%. That’s about as close as you can get! We’ll see if there are any other polls that are issued tomorrow. You would have to say the momentum is with Santorum.
