What is the added cost of keeping thousands of troops on the border?

All. Every…single…penny?

I don’t know. If MSNBC, CNN, or the New York Times ran daily headlines about the threat of, say, West Nile virus or an increase in home invasions or how pickup trucks are more likely to contain homicidal maniacs or, I don’t know, a ■■■■■■■ caravan of poor people in Mexico, such that they just kept pounding it every hour on the hour–fear run fear hide fear buy guns–I wouldn’t change my daily pattern, and I certainly wouldn’t use that news to justify changing my vote, even if some candidate kept stumping over those topics.
