I'm not surprised by that. Shall we cut off our nose to spite our face? I live in a heavily Republican area in a state that often sends delegates to the electoral college for the Democrat candidate. Many of the people who work there are poor and most are solidly Democrat and most of them don't vote unless they felt very, very strongly about it. One sure way to energize them to vote is to effect their jobs. My guess is that many of the people who work in the various Heinz factories that *are* in the US are the same way.
If we want Bush to take Michigan's electoral votes we can't be playing petty games. It may feel good to snub you nose at Ketchup boy's "family" business, but in the end it's counter-productive.
