On the eve of the next big primaries, Hillary Clinton receives a consistent 50 percent of the party’s support in polls and she has accumulated 52 percent of the delegates (772 pledged and 472 super delegates). If the polls are correct, today’s results could seriously challenge the Bernie Sanders theory of winning. In Clinton’s delegates, Super Delegates make up 20 percent of her total. She appears to be ahead in all the upcoming races, but with the closest races in the northern tier of Illinois, Ohio and Missouri.
Donald Trump has not broken 50 percent of his party’s support in national polling, although his consistent 35 percent or more is enough to secure a series of winner-takes-all or winner takes most delegate contests in today’s races. Except for Ohio he appears to have a 10 point or more lead in each contest on March 15.
