CALLED ON A SAT MORNING 11AM WENT TO ANSWERING MACHINE, THEY LEFT NO MESSAGE.
ANNAPOLIS MARYLAND ON THE CALLER ID

This is the 4th call I've had from "TPM ("Tea Party Majority") Fund,"--one every day for the last 4 days,  each time using a different number...which I believe is intended to defeat call blockers.

On 4/8, the number on my caller ID was 242-770-2472
On 4/9 it was 202-770-2360
On 4/10 it was443-252-8196
Today,4/11, it was 410-934-7765

I'm listing it as a political call, but I don't know whether it's really a Tea Party organization spamming my phone, or scammers pretending to be, but I'm not about to answer any of their calls.  But I expect this "caller ID roulette game" to continue all the way up to the election next Nov unless they finally figure out that I will never answer and give up.  Meanwhile, the only thing any of us can do about it is not answer, 'cuz blocking won't do any good...they'll just keep trying using different numbers.

Caller ID says TPM Fund.  I googled that and it stands for "Third Party Marketing"  so I'm assuming it's some sort of investment scam.
