John McCain just arrived in Indianapolis, otherwise known as stop No. 4 on his seven state, 22-hour campaign extravaganza leading into Election Day. So far, there hasn’t been much big news today. McCain is delivering pretty much the same stump speech he’s been giving for the past week or so, hitting Obama as the “redistributor in chief” and talking up his own cred as someone who would enter the job with decades of experience, especially on foreign policy. What’s interesting are the little things. For one, McCain, like many candidates in the final heat of a campaign, is losing his voice a little bit. That’s bad news for the folks for the several hundred people who met him at an airport rally here. Not only are the acoustics pretty bad, but the McCain gathering seems to be positioned directly under the flight path for incoming planes here. So far, four massive jetliners have flown directly over McCain’s head as he has been speaking, making it almost impossible for folks on the ground to hear. That may not be the best news for McCain, who is struggling to keep Indiana from going blue. Polls here show McCain virtually tied with Obama heading into Tuesday. Even so, McCain hasn't spent much time here. Today's visit was only the third time McCain has been in the state since the spring.
