I have been doing some research tonight on the web looking for answers as to who exactly is against the fence building and where the donations to those groups are coming from. I had an interesting thought this morning, building a fence across the whole southern border would severely cripple the cartels ability to bring drugs into the USA, they would be the ones with the most to lose if a fence were built, and plenty of money to fight to stop it. I would like to see who the politicians and activist groups are who are opposing the fence building, and see if any money can be traced back across the border.
