Clinton spent her third day out of the last five days stumping in West Virginia, but her own optimism may have slipped at times.
In the town of Eleanor, W. Va., Sunday night, it wasn't clear whether Clinton tripped over a pronoun or was trying to score points with women voters.
"All the kitchen table issues that everybody talks to me about are ones that the next president can actually do something about, if he actually cares about it," she said at a rally. "He"?
She caught herself. "More likely, if she cares about it," Clinton added.
Publicly, Clinton rejected any suggestion that she drop out and quoted Eleanor Roosevelt, saying, "A woman is like a tea bag. You never know strong she is until she is in hot water."
