Clinton Hangs on in Nevada . But she could still be in for a long slog

Larry Sabato reports:

Clinton is strongly positioned to be the 2016 Democratic nominee. But her path to the nomination remains rockier than she would have hoped. The early voting has exposed several key Clinton weaknesses — among the young, white liberals, independents, and even women under age 45. Clinton’s campaign has to wage her primary battles with an eye to correcting those multiple deficiencies if she is to secure the White House come November.
