If any one of the Dem candidates were to make an issue of the invasion, the loss of jobs (both to non-citizens at home and to outsourcing), the lack of attention to the environment and the infrastructure at home, and the assault on our cultural values by people in the US who don't respect our values, they'd win. Everyone seems to be skirting the real issue, which is our future as a nation, and economy, and a culture. Maybe one of them will wake up.
