ELKO, Nevada (CNN) - Hillary Clinton expressed concern that undue union pressure might play a role in Saturday’s Nevada caucuses, saying that some members are being told they should either caucus for a particular candidate, or just stay home.
“I have some concerns about the process, and I want to be really clear about this to everyone. I am afraid that some people may feel that they can't come, or they shouldn't come, or they can't support the candidate of their choice,” Clinton said at an Elko, Nevada campaign event Friday.
“We know that there are some unions in the south that are telling people who to caucus for... so I am calling on all the candidates and all of the unions to make it clear to their supporters and members that people in Nevada - a free and independent state with a very independent people - are free to stand up for the candidate of their choice,” she said, adding that “There should be no interference with anybody's right to caucus.'
Clinton has been endorsed by twice as many Nevada unions as John Edwards, and more than twice as many as Barack Obama. But the 60,000-member Culinary Workers Union, which has endorsed Obama, dwarfs the others combined in size.
Some of Clinton’s supporters recently filed an unsuccessful lawsuit over caucus voting at casino sites, where many Culinary Workers Union members are employed.
