Gretchen's Take: Who knew Wisconsin would be so pivotal

Tomorrow Wisconsin folks will vote in the primary there. Maybe you didn't know the long history of what makes the badger state a pretty good predictor of who the republican nominee will eventually be. I know I didn’t'. Every GOP nominee for the past 52 years has won Wisconsin. So, if the recent polls are correct, that's good news for Ted Cruz, who in the most recent polls has been up on Donald Trump by as much as 10 points. The big question is whether the change we've seen in the Wisconsin polls is indicative of what's happening across the rest of the country as well.

Check out the IBD/TIPP poll, the only national poll done after Trump's campaign manager was charged with simple battery and after his comments about abortion. Among registered Republicans, and Republican leaning independents, Trump's lead over Cruz shrank from 11 points last month to 7 points now with Cruz and Kasich both gaining 11 and 12 points respectively.

They say politics is often about momentum, who knew the great state of Wisconsin would prove to be so pivotal in this presidential race.
