**note: For the Republicans, each of Wisconsin's eight congressional districts are assigned three delegates (for a total of 24). The top vote-getter in each district is allocated all three of the delegates (so if Trump had won, let's say, in the 3rd District he would have gotten their 3 delegates out of it). In addition, there are 18 "delegates-at-large" which are bound to the presidential contender receiving the most votes statewide. Cruz is being shown as having won in all eight districts so he has added all 24 assigned delegates to his running total.
Cruz is also being shown as the leading vote-getter statewide with almost 50% of the popular vote (the rest being divided between Trump and Kasich) which means he pockets the 18 delegates-at-large as well; he clears the board and exits Wisconsin with another 42 delegates to his credit.
If Trump still intends to win this thing, maybe he should spend less time whining about how Kasich is taking "his" votes and more time trying to figure out how to keep Cruz from corralling them.
NOTE — Update as of approximately 1:00 PM CDT on 4/6 to reflect final results:
Trump is now being shown as the winner in both the 3rd (SW Wisconsin) and 8th (NE Wisconsin/Green Bay/Door County area) Congressional districts — see map — so he has managed to save a little bit of face by scavenging a total of 6 delegates. Cruz is still the statewide winner overall with 531,129 votes/48.23% to Trump's total of 386,290/35.08% (with Kasich finishing a distant third with 155,200/14.09% of the vote) out of a total of just over 1.1 million votes cast.
