Just do it.
What will happen to the Republican party now is what's happened to it in the past -it will win- if two things happen:
1. Voters continue to remain uninformed.
2. People of conscience and ability sit at home bloviating and hoping someone else will do the work of persuading voters and the getting out the vote.
It is not uncommon in any Congressional District of a million people for there to be only a few hundred people active in any political party. That's freakin shameful. If you do not care enough to get actively involved in defeating Republicans and electing progressives- then you are the problem! Anyone can be involved -my crazy neighbor lady makes a mean Lasagna and healthful fruit plates for young campaign staffers. Another shy person prints out all the walksheets and call lists. Other volunteers drive voters to the polls. Wealthy folks contribute. Web people make websites and do social media. Leaders lead. The gregarious folks talk to voters.
Every one of the volunteers I know has a family and a job and other responsibilities -so that is simply no excuse. If you do not volunteer, ask your self: Do you care enough about this country to do something -or not?
