Personally, I abhor his environmental policies. However, I have groups & organizations that I can support who will fight for the environement.
Likewise, I am working through groups & organizations to stop
illegal immigration and amnesty, by bombarding the Senate & Congress with letters, emails, phone calls and faxes. Lots of ground has been gained, although there is STILL a lot of work to be done.
People DO have a voice and can influence government. There are several groups that when you sign up with them, will send you links dircetly to the people you want to contact on whatever issue is coming up in Congress, Senate, White House etc. Can't get any easier, even for lazy folks.
