In Iowa, New Hampshire and now Nevada, the Clinton campaign has sought to suppress the vote of her rivals' supporters.
The headlines say the latest schism among the top Democratic presidential candidates is over gender and race. But on the ground in the presidential season's opening states, there is a darker narrative: that Hillary Clinton will not just fight hard, but fight dirty, to win. And her tactic of choice is attempting to suppress the votes of her rival's supporters.
The latest example is from Nevada, where the Nevada State Education Association is widely seen as filing a suit on Clinton's behalf to stop Las Vegas' most powerful union, Culinary Workers Local 226, from caucusing inside downtown casinos after the union endorsed Barack Obama. The tactic foments a split along racial and class lines in arguably the strongest union city in America.
"It's horrible," said one longtime Nevada activist, who didn't want his name used. "It will cause fights and damage that will last for years."
But the Clinton campaign has made similar moves in New Hampshire and Iowa.
