The circumtances where your state will become a tossup

[Keep cool-idge]

Well we now know that the stuff about republicans needing a popular vote margin of plus 3 in Michigan Wisconsin and Pennsylvania is not true.

[Keep cool-idge]

My state would take the following things to make it a swing state

First of all the republican has 60% or higher approval on Election Day

Second the republican is Winning the popular vote by 6 points

Third of all a popular republican from Washington as the VP cough Dino Rossi cough if he was actually elected governor.

It would take Chicago going the way of Detroit, which would cause Cook County to decline in Population. You would also need the GOP to moderate or go Libertarian on Social Issues, doing so make the Democrats less competitive in the Suburbs.

All you need is cook County to go bye bye and the gop wins.
Romney and trump won Illinois outside Cook county.
