No, he wasn't president yet, he was part of the Congress that allowed the bs preditory mortgages that caused the housing crash. You're real good at blaming Bush for crap that the Congress pushed through in spite of him. And you're so willing to forget Obama was part of that Congress.
You CAN get your number on the do not call list. (cell too) at : https://www.donotcall.gov/ They have 30 days to remove it. Legit telemarketers must put their call list through a program at the registry to keep their license, that is how your number is removed. If they call after the 30 days AND you track the number, time, day, content of the call, input the information on a report at the DNC registry. ( report here : https://complaints.donotcall.gov/complaint/complaintcheck.aspx?panel=2 ) Every infraction after the 30 days allows you to sue them for $1200 PER INFRACTION. More of us have to do this for it to work. Governemnt agencies, Non profits, and companies you have done business with in the last 90 days are exempt. I hope this empowers those who may be frustrated.
