“With less than a month until Election Day, former President Barack Obama is sharply increasing his role in the midterm elections, raising money, cutting ads and hitting the campaign trail as Democrats press into territory he says he never expected to compete in,” ABC News reports.Said Obama: “I don’t want anybody to think this is a sure thing. It’s not. We could end up, all these races that are showing we’ve got a two- or three-point lead or it’s a tossup, we could end up losing all of them by two points.”
