Voters in the northeastern American state of <Pennsylvania> have voted in an
important presidential primary contest. Experts say Senator <Hillary Clinton>
must win to stay in the race. She is expected to win. However, she needs to win
by a large number of votes if she is to narrow the lead of her opponent, Senator
<Barack Obama>. He is ahead in the popular vote and in the number of the
nominating delegates. Ms. <Clinton> says a victory in <Pennsylvania> along with
her wins in <California> and <New York> will prove that Mr. <Obama> cannot win
in states with large numbers of delegates. Mr. <Obama> said that he does not
expect to win <Pennsylvania>. But, he believes he has already cut into her once
large lead.
