Senator Tom Harkin says he’ll hit the campaign trail next month with Howard Dean, a former foe of John Kerry’s. Harkin says this time he and Dean will be campaigning for the Kerry/Edwards ticket. As you may recall, Harkin endorsed Dean right before the Iowa Caucuses this past January. Harkin says in October, he and Dean are going to “hit it hard.” Harkin says “it’s a whole new campaign” because polls show the presidential race is dead even since all the one- or two-point leads either Bush or Kerry have in polls in key states Iowa are within the margin of error. Harkin says he’s been told he’ll be traveling in Iowa, Minnesota and Wisconsin between now and election day for the Kerry/Edwards ticket. Harkin says “these are all vital states” that Bush and Cheney are trying to win, too. Harkin’s statements earlier this summer that Dick Cheney was a “coward” for not serving in Vietnam were thought by some to have prompted the Kerry campaign to distance itself from Harkin and curtail his appearances on Kerry’s behalf.
