The road just got rockier for Hillary Clinton in her battle to win her party’s presidential nomination after Barack Obama’s victory in North Carolina and her slim win in Indiana.

“It’s full speed on to the White House,” Clinton said at a victory rally in Indianapolis, with her husband, former President Bill Clinton, standing behind her. “We’ve got a long road ahead, but we’re going to keep fighting.”

But Clinton made some conciliatory noises. “I can assure you as I have said on many occasions, that no matter what happens, I will work for the nominee of the Democratic Party … and I know that Senator Obama feels the same way,” she said.

Should Clinton drop out of the race for the Democratic nomination?

Presidential candidates John McCain and Hillary Clinton want to suspend the gas tax for the summer to offer drivers some relief from record fuel prices. President Bush said this week that he was willing to consider a fuel tax holiday.

Barack Obama opposes the idea, saying it would not amount to much. House Democratic leaders have also shown little support for suspending the gas tax. Some experts say that a gas tax holiday wouldn’t help drivers much if service stations don’t pass on the savings to consumers.
