Why? Because our sovereignty IS at stake and any politician who is involved with or who supports this NAU/SPP, regardless of party, is a threat to our country and IMO should not be in a position of power. But, that's just my opinion based on what I've already read about it. The 1000 pages released in the FOIA, the frosting on the cake, may disclose the names of those politicians involved and who have wished to remain undisclosed, will be helpful to know prior to voting. I will vote Republican, but not for anyone who supports NAU/SPP and OpenBorders/Amnesty.
The NAU/SPP is, IMO, the very reason that our borders have gone unsecured since 9/11 and will remain unsecured, at risk to our national security.
