Here's what the Obama camp and the Democrats need to do to win this election. It is simple advice that unfortunately Democrats never heed to during a national election
Attack Surrogates - While Obama doesn't need to go negative on McCain he needs surrogates from the Democratic party to do so...mouths big enough that microphoness will be placed in front of them. When the McCain camp or the RNC runs ads juxtaposing Obama's image with pretty white women or subtly claims he is the anti-Christ the Dems need to fight back hard and fast. The Democrats are horrible at this. They let Kerry get Swift-boated and stood back and watched. Okay, maybe they were told to stand back and watch but this time it has to be different: a strong united front of surrogates ready to lay some vicious smack downs.
I doubt the Dems are up for this but if they want to have a rare White House victory without the help of Ross Perot it will need to be done.
Subtle Messaging - Obama and his surrogates need to start the subtle messaging that McCain is not up for the job because he is too old. The McCain camp already brought out the race card with the Britney ad so it is gloves off at this point in time. If I was Obama I would weave the message "Perhaps John McCain doesn't remember...." in just about every speaking opportunity I had. I am sure there are other phrases one could use.
Christian Conservatives - Some front group needs to start reminding Christian Conservatives of all the nasty things McCain said about them in the 2000 primaries. Run ads in Red States that might turn blue. Pushed strong enough, this might keep a lot of folks from the polls in November. And, if McCain is stupid enough to pick a pro-Choice running mate or a Mormon you can use that as fodder too.
