There seem to be two kinds of people:
(a) Those who think investigating the possibility of voting fraud makes us look like whacko consiracy theorists, and therefore is a mistake: "Get a life you sad bastards, WE LOST, quit whining and get over it. Face reality!"
(b) Those who believe voting fraud may have happened, and we must do everything in our power to check for it, even if we initially look like conspiracy theorists: "I'm a computer engineer, I know how easy it would be to hack the election, so I think it was hacked by the Evil Republicans; this could be the end of democracy as we know it. Face reality!"
We don't have to have a wedge driven between the two camps (a) and (b), if we frame things correctly. Here's the frame:
As a matter of morality and principle, we must prove beyond a measure of doubt that voting fraud did NOT occur.
Why is this a good frame?
It allows us push for the on-the-ground investigations without looking like conspiracy theorist whackos. In other words, groups (a) and (b) need not be in conflict. We can unite, and stop bickering once and for all.
Solidarity = Power.
The frame takes the higher moral ground against the Republicans. Our objective is to show that all is well in the Great American Republic, the system works perfectly, and no voter need be disenfranchized. By proving the election was not fixed, we'll put a stop to these dangerous conspiracy theories that are endangering America at a Time of War. You see, our motivation is pure Patriotism.
If we happen to accidently stumble accross some evidence the election was fixed... that will be a "stunning unexpected surprise".
