This race has been ridiculously underpolled. The last non We Ask America poll was in early April.
Pollsters aren't prone to work for free.
There aren't many media groups that want to pay for regular polls here in IL. There will be some polls from the major outlets in the fall during the campaign, but the rest will be smaller buys or internal polling. When media outlets pay for polling they tend to have a long term relationship with a single firm.
That brings in WAA which is native to IL and has moved beyond its original roots as an arm of the manufacturers association. Capitol Fax is the most respected political blog in the state and is the only media outlet currently engaged in regular polling. It uses WAA as the pollster of choice, in part due to the in-state experience. Cap Fax dumped on many of the national pollsters who refused to poll the independent Cohen four years ago for Gov, and that resulted in Brady boosted by the other "not Quinn" votes. Like any good business, WAA will work with their client to ask the questions the client wants. It's worth noting that the Chicago Sun Times, the more left-leaning of the two major newspapers in the city, also now uses WAA for its polling.
