Senator Hillary Clinton revived her presidential campaign and prolonged fight with rival Barack Obama for the Democratic nomination with twin triumphs in the Texas and Ohio primaries, Bloomberg reported Wednesday.
Clinton had 51 percent of the vote in Texas to Obama's 47 percent with 85 percent counted. In Ohio, Clinton was winning 55 percent to Obama's 43 percent with 91 percent counted.
The New York senator also prevailed in Rhode Island, where she took 58,4 percent of the vote to Obama's 40,4 percent with 98 percent counted. Obama won in Vermont, taking 59,8 percent to Clinton's 38,3 percent with 86 percent counted.
On the Republican side, Senator John McCain of Arizona clinched his party's nomination by racking up four more wins over former Governor Mike Huckabee of Arkansas, who has officially announced he was ending his campaign.
While the day's results were welcome in the Clinton camp, she barely cut into Obama's overall lead of more than 100 pledged delegates.
"We both still have nearly the same delegate lead and we are on our way to winning this nomination,'' Obama said.
Clinton's victories in three of the four states voting on Tuesday ended Obama's 11-contest winning streak. Now she is to head into the next big test on April 22 in Pennsylvania.
The next states to hold contests, Wyoming on March 8 and Mississippi on March 11, are likely to increase his margin.
