asking GOP voters why they haven't organized a protest spectacular w/ tons of bodies is like me asking you, "Why aren't you running a marathon? why aren't you running a marathon *right now?*"
Why don't Republicans train their people to do this stuff? Partly bc it's not their culture, but partly bc when normal people know how to apply pressure they use those skills to pressure their leaders.
(It's not how it works in the Dems, either.)
Think more Couch to 5K.
Where do you go regularly to be in a meatspace group of people who think like you?
If you don't: that, not mounting a spectacular protest, is your challenge.
