I am a supporter of Ted Cruz, but I am not a supporter of calls to solicit money for campaigns. I block once I come on 800 notes and find out who is calling.
I had two calls with ID "TEXAS42" using two numbers, 1-218-275-7386 and 1-210-876-2087. I agree with "baffeled" it seems to me to be "more than that" ... in fact, I seriously doubt it's the political campaign of Cruz. I did not pick-up either call and neither call left a message, as they had the opportunity to do.
