---"Ms Topinka carried DuPage by a far greater margin that the rest of the state last month."---
And yet, every Topinka voter I have encountered was a Democrat in DuPage.
I hope she doesn't actually have that much crossover appeal......sheesh!
I severely doubt there was a massive crossover in the GOP primary in DuPage seeing as the Dem primary for the 6th congressional district was one of the most expensive and high profile events statewide, and even to a lesser extent nationwide.
