wendyzski probably has it right: turn off the ringer until after S(t)uper Tuesday. There have been a few calls. Some of them even connected. Ron Paul is using some automated set-up.
And that earlier polite call from the Romney folks? Today it was utterly cancelled out by another call from Romney folks (live person, again) that didn't say why to vote for Romney, but went on and on about why to vote against McCain.
Actually, the way things seem to be, I don't see anyone to vote for. But I still don't like having a campaign try to tell me who to vote against.
