Ted only needs to win 94% of the remaining delegates to go into the convention with 1237 delegates.
Trump was never expected to win Wisconsin. Wisconsin is a relatively small number of delegates. The only reason Wisconsin has been hyped is in order to further a narrative. That narrative is “the end of Trump”. We’ve been hearing that for many months now yet it hasn’t happened.
Any delegates that Cruz gets from Wisconsin will be hyped as if a huge number of delegates have been won, dovetailing with the narrative that this is “the end of Trump”.
The fact is that Cruz is a distant second. The chance of him having 1327 delegates is practically zero. The best case scenario for Cruz is that any delegates picked up in Wisconsin, even all of them, only delay the demise of his campaign.
