After the primaries and caucuses in February and March are concluded, about 57 percent of pledged delegates have been awarded while roughly 43 percent are still up for grabs within the next two months.
While Mrs. Clinton still holds a clear lead, after “Big Tuesday” (March 15 primaries) Sen. Sanders managed to narrow the delegate gap from 16 to 10 points, from a 58-42 to a 55-45 deficit by winning big 5 out of 6 states in ”Western Week” (March 22-26 primaries).
The pattern that electoral strengths and weaknesses of the candidates differ a lot depending on the region seems to continue — at least for now: Sen. Sanders expanded his lead in the West, continues to lead in the Midwest and Northeast, but loses big in the South.
All in all Mrs. Clinton remains the clear favorite in the nomination race. If Sen. Sanders wants to have a shot at a pledged delegates majority, he would have to win most of the remaining states by double digits — i.e. he should start today with a double-digit win in Wisconsin.
