See "actions to protect the American worker", essentially, isolationism. Anti NAFTA, anti TPP, anti China dumping, anti UN regulations (ie. anti climate change, or at least anti economic impact from climate change).
In the last section there's something about working to punish people employing illegal immigrants, which is a very sore point with poor Americans.
These are not going to be very popular actions on Hacker News, but is it that hard to see that there's a TON of poor Americans this would resonate with ?
