1500 or >
I just made my own simulator. I put the remaining states in a spread sheet along with their delegates. I’ll read the rules for each states and come up with numbers. Most of the states are Winner-Take-All and Winner-Take-Most. It was proportional until the 15th of March, but winners now get lion’s share of the delegates. Trump will comfortably win 600, and likely more, of the next 1003 delegates that are left, and anything after that will be extra gravy.
