Bernie Sanders projected to win 2 states against Hillary Clinton

Hillary Clinton and Sen. Bernie Sanders fought Saturday's Democratic presidential primaries and caucuses to what seems likely to be a virtual tie.

Of the three nominating contests held on Saturday, Sanders won Kansas and was projected by NBC News and CNN to win in Nebraska.

But Clinton is expected to do well in the Louisiana primary, a contest worth just under the number of delegates of Nebraska and Kansas combined.

Though his wins may inject some perceived momentum into his bid following a string of losses earlier this week on "Super Tuesday," Sanders faces an increasingly difficult electoral map going forward.

Sanders may pick up a victory in the Democratic caucuses in Maine on Sunday. But Clinton led in almost every reliable recent poll of states voting on March 8 and March 15, when another substantial chunk of delegates will be awarded.
