HERSHEY, Pa. (AP) — John McCain repeatedly implores backers to “stand up and fight” these days, showing gritty determination even as many indicators point to a Barack Obama victory and Republicans engage in fingerpointing typical of losing campaigns. “Nothing is inevitable here. We never give up. And we never quit,” McCain said. A week before Election Day, the Republican is an enthusiastic underdog with what advisers say is a deep personal belief that he still has a chance to stage an upset next week. He has come back from the brink politically and personally before, and they say he’s resolved to do so again despite steep challenges. In the homestretch, he tells people to ignore the pundits who project an Obama win and polls that favor the Democrat.—-Contact The Daily Reveille’s news staff at [email protected]
