GRAFTON, WV - Hillary Clinton celebrated Mothers' Day with her daughter Chelsea in the holiday's ancestral home - using its founder as a message of perseverence for a campaign that's hanging on by a thread.

"I think it's interesting that this holiday we start today was the idea of a woman, right here in Grafton," she said. "Anna Jarvis prevailed against the odds. If you were to come up with an idea right now for a national holiday, and you persevered for nine or ten years like she did, it would be a labor of love. And that's what it sometimes does take to make the changes that benefit us."

Part of the inspiration to persevere against her own long odds, she said, comes from messages from her supporters telling her to keep her head up and forge ahead. "Over the past few weeks I've gotten emails from around the country from people offering words of encouragement and advice," she said. "One man from California wrote 'keep fighting. No matter what the outcome may be, the fact that you stood throughout the constant ups and downs of the race, one thing is sure - you never wavered and you never gave up.' "

At that, the crowd cheered - and one man loudly yelled "don't give up!"

Hillary continued, "My favorite message was from a woman named Angela. 'Keep strong,' she said. 'It's not over until the lady in the pantsuit says it is.' "

Clinton is spending the next few days in West Virginia, where the campaign hopes a big win can give her some momentum. But with a big win already expected due to the large white, blue collar base in the state, any result here is unlikely to have much impact on the state of play.
