Samuel Wilson guest blogs at EconLog on the political externalities of immigration. Preliminary results of the investigation: immigrants and their kids and grandkids have basically the same political preferences as native-born Americans.
Exceptions include a desire for less military spending, more foreign aid spending, and more local infrastructure/mass transit.
In terms of the euvoluntaryness of immigration, these results suggest that perhaps the uncompensated externalities portion of anti-immigration sentiment is less powerful than folks might otherwise imagine.
Pity the post is a tad on the tl;dr side. Someone needs to teach the author how to write blog posts.
