From NBC News:
RECAP: Sanders and Cruz in Wisconsin
Republican Ted Cruz and Democrat Bernie Sanders won Tuesday's primaries in Wisconsin, dealing setbacks to frontrunners Donald Trump and Hillary Clinton and giving both winning candidates a burst of momentum as more delegate-rich contests loom in a matter of weeks.
Cruz and Sanders had each led in public opinion polls leading up to Election Day. Cruz has the opportunity to take all of the state's 42 delegates. However the Democratic race awards delegates proportionally, and Sanders is likely to earn just a handful more then Clinton.
If the next president has to be a Democrat, I would much rather it be Sanders than Hildebeast. Leaning towards Ted Cruz and may seriously vote for Sanders if Trump gets the nomination.

Neither Cruz nor sanders will be permitted to win.
