(CNN) – With only three primary contests remaining in the prolonged race for the Democratic nomination, Hillary Clinton is stepping up her efforts to convince potential voters and the party's superdelegates that she is a stronger general election candidate than Barack Obama.
In a particularly spirited speech Tuesday night at a Montana campaign event, the New York Senator suggested Obama is much more likely to lose to presumptive Republican nominee John McCain next fall.
"We have not gone through this exciting unprecedented historic election only to lose," Clinton said at an event in Billings, Montana.
"You have to ask yourself who is the stronger candidate?" she continued. "And based on every analysis of every bit of research and every poll that’s been taken and every state that a democrat has to win, I am the stronger candidate against John McCain in the fall."
It was not immediately clear which polls and states Clinton was specifically referencing.
Recent polls out of the crucial swing states of Ohio, Pennsylvania, and Florida have indicated she has a better chance of beating McCain in those places than Barack Obama. But the Illinois senator performs better is several other swing states that Democrats have historically had difficulty winning, such as New Mexico, Nevada, and Colorado.
