GASTONIA, North Carolina (CNN) - Three days before the North Carolina and Indiana primaries, Hillary Clinton laid out the differences between herself and Barack Obama, attacking his voting record and his rejection of her proposed "gas tax holiday."
"I understand my opponent disagrees with me, he doesn't want to give you a gas holiday, he doesn't want to go after the oil companies. He wouldn't vote against them with the 2005 Dick Cheney energy bill and I did," Clinton told supporters.
"Sen. Clinton's been using this issue to make the argument that I'm somehow out of touch," Obama said earlier Saturday at a rally in Indianapolis. "Only in Washington can you get away with calling someone out of touch when you're the one who thinks that thirty cents a day is enough to help people who are struggling in this economy."
Obama has seized on the issue, pointing to analysts who say the legislation to tax oil companies' record profits is flawed. They argue that it would either have little impact or it would have a negative effect by either causing drivers to drive more or oil companies to
simply raise their prices.
Obama also made fun of the questions surrounding Clinton's plan, saying she could only find an oil lobbyist to go out and support it.
"The Obama campaign must be bitter about sliding in the polls and is clinging to these gas tax attacks out of frustration," Clinton spokesman Doug Hattaway responded.
Clinton said that her biggest difference with Obama is over health care, arguing that his plan isn't universal and leaves 15 million people uncovered. She also took him to task for not supporting her efforts to place a moratorium on home foreclosures.
"We've seen this from him before," Clinton said in Moorseville, North Carolina, about the candidates' division over the gas tax legislation, "instead of attacking the problem, he attacks my solutions."
