By 2012 all campaigning may be done by video. Evidence? Here's a video communication from Obama to his supporters warning them of overconfidence.
Keep an eye on the guy on the bike.
The polls in Pennsylvania are showing no consistent trend - other than an Obama advantage - despite the intensive attention being paid to voters by McCain and Palin.
For the past week, Obama has held a lead marked by its fluctuation from 4 percent to 14 percent. One piece of evidence that may indicate some gains by McCain is that the latest poll, by NBC/Mason Dixon and in the field on Oct. 27 and Oct. 28, gives Obama the 4 point lead.
But a Marist poll, done the 26th and 27th gives Obama a 14 point lead.
Those fluctuations explain why McCain has hope, and Obama is releasing videos like the one above. The average of all recent polls gives Obama a 9.5 percent lead.
