Meeting with about 100 supporters in Brownsburg, Ind., Clinton said she was a bit offended about people who don't need help filling up their gas tanks telling people who do that they shouldn't get a break.

Clinton also noted that while Democratic rival Sen. Barack Obama, D-Ill., opposes the idea, it has been embraced by presumptive Republican rival Sen. John McCain, R-Ariz..

The Indianapolis Star said Clinton chided McCain for not backing her idea of a windfall profits tax on the oil industry to make up the lost tax revenue.

"I sort of feel like Goldilocks," Clinton said. "Not too much, not too little. Just right."
