* Two events have helped create a minor buzz about Republican Congresscritter Judy Biggert’s reelection chances. First, Biggert’s Democratic opponent Scott Harper raised almost as much as she did in the recent reporting quarter. Then, CQ Politics made a minor adjustment to her ranking…

• Illinois’ 13th (New Rating: Republican Favored. Previous Rating: Safe Republican). Republican Rep. Judy Biggert , who has centrist GOP leanings, has been very politically secure in a mostly Republican-leaning district that includes Naperville, Bolingbrook and other suburbs southwest of Chicago.

But she may need to keep an eye on Democratic businessman Scott Harper, who already has raised more money than 2006 Democratic nominee Joseph Shannon, who won 42 percent of the vote in what was the best showing by a Democrat against Biggert in her five terms. Harper’s campaign is serious enough that he’s attracted contributions from Illinois Sen. Richard J. Durbin and Rep. Jan Schakowsky.

The Democratic Congressional Campaign Committee (DCCC), the political arm of House Democrats, hasn’t included Illinois’ 13th on its lists of highly competitive Republican-held districts, and Biggert still is strongly favored. But this a race to keep an eye on for signs of increased competitiveness.

That last graf is the most important. CQ is just saying that the race might be tighter than first thought.

* And now, Biggert has released a poll to try to tamp down the buzz…

Republicans are seeking to downplay any talk that Rep. Judy Biggert (R) could be in a competitive race after her opponent outraised her in the second quarter, and they passed around an internal poll Wednesday that showed Biggert way ahead.

The Biggert poll, conducted by American Viewpoint Inc., was done in mid-June and showed the incumbent holding a 55-30 lead, with a job approval rating of 67 percent.

Democrat Scott Harper’s campaign disputed those numbers, citing its own polling data, which it says shows the incumbent’s job approval below 50 percent.

Three things: That Biggert survey is a pretty old poll. However, note that Harper’s campaign didn’t relase the head-to-heads or even “deserves to be reelected” numbers. And, Rod Blagojevich’s job approval was way below 50 in 2006, meaning that this number, in and of itself, is not a great guage.

* Meanwhile, the Sun-Times is playing catch-up to a story that’s been bubbling around the blogs for a while now…

Concrete mogul Marty Ozinga’s companies racked up $59,000 in unpaid taxes over the last 20 years, according to documents provided to the Sun-Times by political operatives.

The tax liens have been filed against the Republican congressional candidate’s companies in Illinois, Wisconsin and Indiana. Some are fines on his trucks that pour concrete in Chicago.

The response is a bit weak…

Ozinga’s campaign notes his Democratic opponent, state Sen. Debbie Halvorson was fined $44 after being late on a $910 real estate tax payment for her Springfield condominium. She also was fined $25 for letting a corporation she founded lapse after not using it.
