For her part, Clinton emphasized plans to turn around the troubled economy as she campaigned in Pennsylvania.
In satellite interviews with TV stations in North Carolina, Montana and Indiana, she also accused the Obama campaign of trying to pressure her to withdraw and trying to deny a voice in the nomination process to voters in those and other states with upcoming contests.
"A lot of Sen. Obama's supporters want to end this race because they don't want people to keep voting," Clinton told a station in Billings, Mont.
"People don't want this election taken away from them by the media or somebody sitting in an office in Washington," she said.
Asked about the length of the marathon campaign, she quipped: "It's one of the longest things I have ever done. It's longer than being pregnant."
