Americans Most Likely Don't Care About DHS Shutdown/
I am not sure many Americans care about DHS shutdown. The hatred for public employees seems like it is at an all time high. RW hate radio implies that evil public employees should be jailed or something. All you hear is how unAmerican and evil overpaid and lazy public employees are. Just listen to Rush, O'Reilly, Hannity, Fox or any of the rest of hate media across the country.
TSA is often portrayed as useless and inept. They may not be perfect but they had to be a lot better than the privatized security that let the terrorists board the planes on 9/11.
Besides the GOP was rewarded in 2014 after the previous government shutdown. It did not effect their fortunes whatsoever. They gained hugely. So their take is they will not suffer for this shutdown. Sure the shutdown did not come up during the election most likely because voters did not see it as an issue. Abortion, small government, and race hatred was more important.
