With 63 million Trump voters, it can be done!
But realistically, it might not achieve the financial goal (or it might), but the fact that there are 100,000 donors already, and its just getting started, it DOES make quite a huge statement.
While the media downplays the support for the wall, people are putting their money where their mouth is and showing support for the wall. I donated - not a lot, but it's the least I could do. Better than wasting money on a lottery ticket or supporting yet another RINO candidate.
The money perhaps could be ultimately best spent lobbying for the wall.. I put in a nominal amount, just to be counted.
