Indeed.. We must also ignore the third party trolls..
Agreed. Beside the usual involvements in campaign, I suggest one way that can be done from home: create an account in yahoo, gmail, or whatever that gives you email address. Then, write a comment on internet news that you are comfortable to access, espcially the one that doesn't require you to register first. I often wrote something along my tagline below, or comparing Obama (running for presidency) with Palin (running for vice presidency). Don't bother to back-and-forth debate, as many sites don't allow you to do so. What's important is our side's message is out. Don't spam the sites either, as nobody likes to see a same message again and again.
