Does "country of origin" influence your purchasing decisions?

This question is aimed primarily at those of you in the US, but I welcome the comments of all.

Weathertech spent a fortune on a Superbowl advertisement that touted the fact that against conventional wisdom (“you can’t do that”) they were able to build a factory in the US, manufacture a successful product and provide 1000 steady jobs. In the big scheme of things it is only one company, product line and a small percentage of the unemployed in the US; is this the beginning of a trend? should it be?
