The caucus format will benefit both Ted Cruz and Bernie Sanders. They don't mean a whole lot.
Ted Cruz (R-Calgary) has won Kansas and Maine caucuses. However, for the Maine caucuses, he did not win 50 percent or more, so he, Trump, and Kasich wound up with delegates.
Sanders has won Kansas and Nebraska caucuses for Dems.
Trump has won the Louisiana primary and Kentucky caucuses.
Clinton has won the Louisiana primary.
