Presidential candidates John McCain and Barack Obama are fighting the last battles of the elections war. The two candidates are making appearances in key states as the election day (Tuesday) is nearing.

The Republican candidate, John McCain, will hold rallies in Virginia and Pennsylvania, while his vice presidents running mate, Sarah Palin, has scheduled similar appearances in North Carolina and Florida. The Republican Arizona Governor will also appear on the “Saturday Night Live” comedy TV show.

On Friday, Senator McCain received a stimulating introduction from California Gov. Arnold Schwarzenegger in Columbus, Ohio, a state where he trails in the latest polls. Mr. Schwarzenegger emphasized his colleague’s readiness to lead the United States from the White House.

"John McCain has served his country longer from a POW camp than his opponent has served in the United States Senate," said Schwarzenegger.

On the other side of the “barricade,” Illinois Senator Barack Obama will deliver the weekly Democratic radio address Saturday and has scheduled rallies in Colorado, Missouri and Nevada. He will be aided by his running mate, Delaware Senator Joseph Biden, who will hold similar rallies in Indiana and Ohio.

While the republicans attack Obama because he is allegedly not ready to be the U.S. President and the country isn’t at all in a state that permits its president to take time and get use to his job, the 47-year-old Illinois Senator accuses McCain of offering what he called the "same worn out" economic policies that the country’s current president, George W. Bush, has been offering.

However, Obama continues to lead McCain in public opinion polls and many analysts and experts of the election process believe that McCain has run out of time.
