Conservatives squawking about border issues and refugees should take a close look at the Mexican agriculture sector that was devastated after the passage of NAFTA. Farmers who were able to support themselves before NAFTA weren't able to afterward. When a foreign government can undersell domestic farmers - you're left with few alternatives.
If your skeptical of the TPP, you have a good reason to be so. We've seen this song and dance before with NAFTA. Could we at least let our senators read the bill? Corporations got to look it over.
