The thing with the charities & political org. is that they are not governed by the do not call list (at least in our state).
I donate where I can but I can make up my own mind about which charities to give to and who to vote for.
I REALLY dislike the charities that start out with "you were so generous last year /you won't have to send it in for 2 weeks or whatever time span, when I know I haven't ever given them anything. I looked into caller ID and for me it would be $5 a month, I should not to pay to avoid the harassment.
