Once again: New York votes on April 19, and we have northeastern primaries (MD, DE, CT, etc.) on April 26. April will be a very good month for Trump, his delegates lead will be bigger on April 27 than it is now.
The Cruzers are trying to treat Wisconsin like Iowa - basically pretending winning it alone with one the nomination - but the reality is it won't erase Trump's delegate lead, it won't influence how New York and those other states vote later this month, and it won't change the fact that Wisconsin, should Cruz win it, will likely be his only win in the entire month of April.
The rest of Wyoming's bound delegates (14) will be chosen Thursday 14 April - Saturday 16 April 2016. Since Cruz won that state in a blowout, I have no doubt that he will pick up all of those. Colorado's 37 delegates can be bound or unbound. Cruz won 6 today, with the rest voting throughout the week to be bound to a candidate, or remain unbound. It doesn't look good for Trump.
Wisconsin remains to be seen, but it looks like a win for Cruz. Who knows how big a win it will be.
So, before New York, there will only be 715 available unbound delegates left. Trump needs 485 at this point, so you can clearly see, Wisconsin is pretty important for Trump too.
If he gets mostly shut out in Wisconsin and Colorado, we are almost certain to be headed to a contested convention.
I meant 808 bound delegates available, not unbound.
