As a service to Kos users, I offer up this handy dandy template for the times when that chip on the shoulder gets unduly burdensome.
I'm a member of the {insert your concern) community. Because of the (insert your concern) community, (insert name of congressman, Democratic Party, President Obama) got elected, and now he/she/it is totally not listening to the (insert your concern) activists. No more money/support/organizational efforts are going to be made for (insert name of congressman, Democratic Party, President Obama) until our concerns become the first and foremost policy priority of (insert name of congressman, Democratic Party, President Obama) in proposed legislation, speeches and policy priorities.
We will not be thrown under the bus again just to satisfy (insert Blue Dogs, moderates, independents, GOP obstructionists) in the name of bipartisanship. In order to send our message, we're willing to burn down everything because progress isn't being made fast enough!
