This coming Sunday the 15th there will be a debate between Bernie Sanders and Joe Biden starting at 8:00 pm Eastern time and it will be a good occasion to compare where the two candidates stand on key issues, especially now that chronic interrupter Pete Buttigieg has bowed out and we will be able to hear what each person says. Unfortunately, the debate will be hosted and moderated by CNN which has not covered itself with glory so far in its political coverage, so we can expect the questions to be inane and slanted in a way that disparages Sanders, just like the last time the network moderated a debate.

Then the following Tuesday the 17th there will be four primaries in Arizona, Florida, Illinois, and Ohio for a total of 577 delegates. In 2016, Hillary Clinton won all four of them suggesting that this will be difficult terrain for Sanders before the subsequent primaries where he has a better chance.
