PHILADELPHIA, Pennsylvania (CNN) - As Sen. Hillary Clinton's underdog campaign soldiers on through Pennsylvania, Indiana and North Carolina, she has begun casting herself as a champion of democracy.
"There are some folks saying we ought to stop these elections," she said in Indianapolis, Indiana, on March 29 as the audience booed the notion. "I don't think we believe that in America," she said. "The more people that have a chance to vote, the better it is for our democracy."
As Pennsylvania's primary nears, Clinton's staffers have increasingly accused Barack Obama's campaign of trying to disenfranchise Democrats. On Monday, in a satellite interview with a television station in Montana, Clinton herself made the charge.
"My take on it is a lot of Sen. Obama's supporters want to end this race because they don't want people to keep voting," she told KTVQ in Billings, Montana. "That's just the opposite of what I believe. We want people to vote. I want the people of Montana to vote, don't you?"
It is a growing theme in Clinton's stump speech as she makes her way through upcoming primary states: that she alone, up against rival forces aiming to silence the millions of voters in the 10 remaining primary and caucus states, will stand up for their right to vote.
