* Democratic congressional candidate David Gill has a new testimonial ad…

That move probably shows the Republican ad barrage is working. He needs to build up his positives again.

* Two competing partisan polls have completely different results…

David Gill has a 9 percentage point lead among likely voters in the 13th Congressional District race, according to a poll paid for by the Democratic Congressional Campaign Committee.

But the campaign of Republican Rodney Davis said Tuesday that its polling gives Davis a 43 percent to 39 percent lead over Gill. The Davis poll, taken by the Virginia firm Public Opinion Strategies, was of 400 likely voters. It has a margin of error of plus or minus 4.9 percent, putting Davis’ lead within the margin of error.

The Republican poll gives independent John Hartman of Edwardsville a 10 percent share of the vote, and says that 8 percent are undecided. […]

An earlier Anzalone Liszt poll of the race, taken in September but never released publicly, reportedly showed the race a tie at 41 percent. And an earlier Public Opinion Strategies poll, taken in early October, also showed the race a tie. An August poll for the Gill campaign by Victoria Research gave the Democrat a 6-point lead, but all polls since have showed a narrower margin. A We Ask America poll of 1,253 likely voters earlier this month gave Davis a small lead.
