Letters to the editor - it's pretty much standard that they are printed, no matter how liberal the paper...that's one avenue.
support our avenues of information like Hannity, Rush, FOX...
don't turn on seeBS, don't watch Matthews, etc...let the ratings go down. You can keep up with their shenanigans on line - without giving them a "listener" on the station. Write to the advertisers of their shows and complain...they listen.
Stay informed via net news and FR ;o)
"share"...most people don't have/take time to be informed and will believe whatever they hear or read. Be ready with facts to refute, in a non-confrontational way...
be involved with your local republican clubs...
just some suggestions
Those aren't bad ideas but I think we need more. I'm trying to figure out what that might be. I think Horowitz might be the most well known figure to maintain the level of activism that we need, or at least that appeals to me.
