Tomorrow in Wisconsin, the wild and crazy 2016 presidential nomination process will gain some clarity.
On the Republican side, the surging Ted Cruz will attempt to extinguish Donald Trump 's momentum. Trump still has the best chance the wrap up the nomination, but without Wisconsin the path becomes murky. Cruz must win Wisconsin in order to keep his own frail hopes of winning the nomination outright alive. Kasich at this point is trying to spoil both Trump and Cruz's path to 1,237 delegates.
In the polls, Trump was winning Wisconsin but has seen his advantage turn into a deficit. Trump has suffered through several tough campaign weeks and needs a solid win to shake off the malaise that threatens to engulf his campaign.
On the Democrat side, Bernie has quietly put together a winning streak that he needs to extend. Hillary still has a comfortable lead, but a Wisconsin win would put Bernie in position to challenge her in New York.
Both Hillary and Trump need a victory tomorrow to solidify their leadership status. Both Sanders and Cruz need solid wins in order to have shot at overtaking the front runners.
