Any way you look at it, these were three very different events.
The "Restore Honor" rally was planned to feature and honor traditional American values that the people know made this country the great nation that it is--the values that the former generation has not done a good job of teaching to this one. The people came voluntarily without coercion, without reward, without compensation, at their own expense to participate and the size of the crowd was astonishing and heart warming to those of us who believe in the values honored. There were no more than a tiny handful of political T-shirts or signs in sight, the crowd was respectful, enjoyed themselves immensely, and left the public grounds clean as a whistle.
The "One Nation" rally was obviously an orchestrated attempt to show up and diminish the "Restore Honor" Rally, and it miserably failed to do so despite coercion from the unions and other organizations. It featured a host of political, including hateful messages on T-shirts and signs along with a string of speakers who proceeded to trash George Bush, Republicans, conservative principles and conservative people, and they left the public grounds in a horrific mess including trashing the war memorials.
The "Restore Sanity" rally was also obviously an orchestrated attempt to show up and diminish the "Restore Honor " rally but at least was done so with mostly humor. Plenty of hateful anti-GOP, anti-conservatives etc. T-shirts and signs were present but there were also those who got into the spirit of the event and just had a good time. Because national figures helped bribe and bus folks into the rally, it was well attended. And apparently they did pick up most of the trash.
I would guess very few votes were affected by any of these events. But the only one that had a positive and lasting effect was the inspiration promoted by the Restore Honor Rally. I, for instance, was encouraged by hundreds of thousands of people who showed up for nothing other than to celebrate what is good in America. I don't think I am alone.
