Who called from 3076557549

I get daily calls from this number with a pre-recorded message about politics.  The caller ID on my phone says
"NEWTGINGRICHTPC."  If calls like this are an attempt to get votes then this is a failure.  These calls are annoying and are made either very early am or very late pm.  Wish these calls would stop!

I got a call this morning from this number.  Said Newt Gingrich was calling.

Who is this?  They keep on calling and don't leave a message.

Calls from this number and similar numbers. Called I'd says Poll C   No idea who this is. Never answer these calls

I called them back and it is "Principled coalition".  A political group.
