I and many others do and have often done so. I'm on several conservative and/or Christian alert lists. I send regular e-mails to companies and my governmental representatives, both federal and local. I write letters to local papers and my school board, too. Sadly, there's just not enough conservatives making the effort. Yet.
Good for you. I wish we’d all get our acts together better on this. I suppose we’re all too busy with families & jobs to do it as well as the leftists.
