I don't think anyone cares whether Dave Marsden's supporters are writing letters to the editor falsely saying they are newly involved in politics. If you think letters to the editor turn a campaign, you've got rocks in your head. In fact, most people just tune them out anyway. So the opponent caught you red-handed. So what? That's what opponents do, even if they didn't really catch you.
I don't even think Earnie Porta has "hit a home run" with his commuter Race to DC. NLS, go try to campaign at a Metro station and see how many growls you get from people whose daily commute you are interrupting. In fact, this stunt may backfire if campaign workers start competing with daily commuters for precious space on already-crowded VRE trains. This is campaign showmanship and Porta needs to do more than this to upstage his opponent, who is a master of little inconsequential issues herself.
More and more, I think NLS is making some "rookie mistakes." He's attributing way too much importance to the shots campaigns fire across each other's bows but voters don't tune in to. Stepping back and taking a look at the big picture, most of this stuff doesn't matter. In some cases, even campaign mailings and advertisements have little effect, especially in a climate where voters reach a "saturation" point. The only thing that matters in most campaigns is who gets a door knock or who sees the candidate at the summer festival he attends every year. That's what turns a campaign. Rozie calls it the "ground game," I call it "boots on the ground" (military tendencies die hard).
If you can get a dedicated bunch of people who follow you to community events and knock on every door in the district, you can win a race. Even without two nickels to rub together. Letters to the editor don't mean a thing, yard signs are a waste (unless you are totally unknown) and mass mailings only count if you are smart enough to send them before mailboxes get flooded.
There you have it. The words of the master, spoken to you.
