* From We Ask America…

Our Illinois Democratic Primary presidential poll shows Clinton with a formidable 57% to 28% lead over Bernie Sanders. Clinton’s only relative weakness was among Collar County Democrats where she leads Sanders 49% to 43%. As we’ve seen elsewhere, African American voters strongly favor Clinton 69% to 14% over Sanders, although the Vermont Senator shows much stronger support among Hispanic and Asian voters. In the Illinois Republican Primary, Trump leads with 38% over Marco Rubio (21%) and Ted Cruz (16%). Rubio has surged over the last three-four days…I’m not sure if it will last. Trump wins consistently in all four Illinois regions, and holds a 9 percentage point stronger lead among males than females (43% to 34%). Trump’s strongest numbers stem from the 1-of-3 GOP primary voters, and there’s speculation that some who haven’t voted in primaries in the past will come out for him. We’ll see.

* Regardless of the results, keep in mind that presidential races at this stage can change pretty quickly. If Rubio continues surging, then maybe he’ll make it close. But I’d rather be the Trump campaign than any of the others right now.

Clinton’s numbers are about the same as other Illinois polls we’ve seen, while Sanders’ numbers are worse. Maybe that’s because of Clinton’s Nevada win, which gave her some momentum. African-American voters tend to break late, which could also help explain it. But, whatever the case, primaries are not easy to poll, so never bet your life on any one result.
