* My syndicated newspaper column drills down into the numbers to see what’s behind those polls released last week…

While the Republicans say the pollsters are contacting the wrong people, the fact remains that three polls released last week had the Illinois governor’s race within 2 percentage points. And five polls released in the past month have shown it to be a single-digit race.

The Chicago Tribune’s pollster had Democratic Gov. Pat Quinn leading Republican state Sen. Bill Brady 39 percent to 38 percent last week, which is a narrower margin than its 5-point Brady lead a month ago. A CNN/Time poll had Brady up by 2 points, and a Democratic Governor’s Association poll had Brady up by 1 point. Public Policy Polling had Brady with a 7-point lead.

The Republicans say the “universe” is skewed on all these polls. They believe that Republicans actually outnumber Democrats come Election Day by a narrow margin. At the very least, they say, those other polls just skew too far Democratic.

If the Republicans are right, it would be the first time their party would outnumber or come close to outnumbering Democrats in any Illinois election in a very long time. This is a weird year, so nobody really knows who’s correct at the moment. Still, you need to keep the GOP’s strong objections very much in mind as we head into the final weeks of this campaign.

The other thing to remember is Quinn’s horrific job-approval rating. The average of the four polls that asked the job-approval question (CNN did not) was a 26 percent approval rating for Quinn, while 58.5 percent disapproved of his performance. He’s already vastly outperforming his approval rating, so it will be darned tough to push his own numbers up much higher unless people start feeling better about him soon.

Still, you simply cannot ignore five polls in a month showing Quinn within single digits of Brady. Whether the governor can pull this off is another story.

Why does this race suddenly look so close? For months, polls have shown it to be a blowout for Brady.

I now firmly believe this race has been much closer than I thought for weeks, if not months. The reason why I and others got this wrong is very bad polling.

Every poll published from the beginning of August to before last week had Brady leading Quinn by anywhere from 9 to 13 points.

Well, actually, one poll did show a close race. At the beginning of last month, the Chicago Tribune’s poll had Brady leading Quinn by only 5 points.

That Tribune poll was so different from the others that it essentially was ignored. But then last week, those other polls came out that showed a tighter race than widely assumed, and I noticed something curious. Pollsters who did not include millionaire independent candidate Scott Lee Cohen’s name in their polls showed a far wider gap between Brady and Quinn than those who did.

Last month’s Tribune poll included Cohen’s name in the mix, as well as the other candidates. The polls released last week that showed a tight race included his name as well.

The average of all five polls during the past month that included Cohen’s name is 38.6 percent for Brady and 35.8 percent for Quinn - a roughly 3-point split. The two-month average for polls taken that didn’t use Cohen’s name was 46.4 for Brady to 35.8 for Quinn - an almost 11-point race.

Notice that Quinn’s average is exactly the same in both sets of numbers. Brady’s is different. Why?

In a two-person race, when you attack an opponent, a portion of your opponent’s supporters eventually will cross over to your side. But in races where lots of people are running, when you attack your main opponent, then his or her supporters might end up with one of the other “minor” candidates.

If you drill down into the polls, it appears that significant numbers of women voters left Brady after Quinn’s early attacks and moved to Cohen. Now, I know that sounds absolutely insane, considering the domestic abuse allegations involving Cohen and his arrest for allegedly holding a knife to his girlfriend’s throat. But lots of people still don’t know who and what Cohen is. And the news media has all but stopped reminding them.

Some top Republicans have been increasingly jittery that Cohen might be making this thing a little too close for jubilation. They appear to have been right.

More craziness to come, I’m sure.

* Levi Moore adds…

Finally, maybe Mayor Daley’s retirement from public office did not suck all the oxygen out of the state-wide races - as many pundits predicted. It was thought that the free-for-all for the Chicago Mayor’s Office would shift all attention and resources to that election. But, it may have merely caused Chicagoans to focus more on politics in general.

The last theory is purely speculative. But, the way things looked for him a few weeks ago, Pat Quinn needed any help he could get. With one month to go, the Illinois governor’s race may be less about change and more about whether Illinois’ typical Democrat/liberal base goes to the polls.

That’s certainly part of it. The oxygen was surely sucked out of the coverage, but maybe not out of the interest.

Thoughts?
