Clinton says Penn. proves her viability

WASHINGTON, April 23 (UPI) -- Hillary Clinton publicly pressed her case as the most viable Democratic presidential candidate following her high-profile victory in the Pennsylvania primary.

Clinton made the rounds of the network television news shows Wednesday morning and argued that she has proved she can win the major states that could be pivotal in the November election.

"It's very hard to imagine a Democrat getting to the White House without winning those states," she told CNN.

At the same time, however, The New York Times reported that polls show Barack Obama in a good position in the upcoming Indiana and North Carolina primaries to be held in two weeks.

The Times said Obama's camp said the results in Pennsylvania did not significantly alter the tight race for the nomination. Obama leads in popular vote, states won and pledged delegates.

The Illinois senator focused more of his attention on presumptive Republican nominee John McCain than on Clinton in his Tuesday night concession speech.
