President Bush and Democratic rival John Kerry campaign Wednesday in what both candidates consider as must-win states in next Tuesday's election.
Mr. Bush will be in Pennsylvania, Ohio, and Michigan. Senator Kerry will be in Ohio, Iowa, and Minnesota.
Polls show the presidential race in these states is very close, with less than one week to go before voters make their decision.
On Tuesday in another important state, Wisconsin, Mr. Bush accused Senator Kerry of being weak on terror and Iraq. He also said Mr. Kerry plans to raise taxes on small businesses.
Senator Kerry, who was also in Wisconsin, attacked the Republican president over the disappearance of 350 tons of explosives in Iraq, which he said threatened the safety of U.S. troops.
