This Tuesday, five states will host primaries: Connecticut, Delaware, Maryland, Pennsylvania and Rhode Island.
Frontrunners Trump and Clinton are expected to come out on top of each state, pushing them out even further ahead of their opponents.
It's been a strange primary season, so don't count the underdogs out just yet. A recent Cruz-Kasich alliance and the grit of Bernie Sanders can go a long way to throw off the plans of the frontrunners.
But even if the numbers at the end of Tuesday's primaries don't signal a curtain drop, it certainly makes it feel like the end is nigh.
