Talk about a wrong number

As longtime registered Democrats, the spouse and I were greatly surprised, and amused, to start receiving calls during the last presidential election from various Republican candidates, the Republican party, and Mitt Romney. 

I actually picked up the phone a few times, to tell them to stop and put us on the "do not call" list, but most of the calls were robo-calls. 

If that wasn't bad enough, now we have the Tea Party calling us. (Thank Cablevision for Caller ID.)

WTF?

Which made us wonder, Do these people not do their research? And if they did, are they desperate or delusional? And if the latter, do they really think that calling us during dinner or at bedtime is going to endear us to the cause?

For that matter, do any of these politicians, pollsters, survey companies, telemarketers, and nonprofits really think, especially in the age of Caller ID, that people are actually going to pick up the phone, during dinner or when they are putting kids to bed -- and give them money? (I feel a bit bad for the nonprofits, but there are other, better, less in-your-face ways of reaching people, like email.)

Thoughts?
