that turns out not to be the case

In Paul Krugman's column yesterday, he notes that Toyota has decided to build a car factory in Canada and explains that tax cuts and Republicans are to blame:

Modern American politics is dominated by the doctrine that government is the problem, not the solution. In practice, this doctrine translates into policies that make low taxes on the rich the highest priority, even if lack of revenue undermines basic public services. You don't have to be a liberal to realize that this is wrong-headed. Corporate leaders understand quite well that good public services are also good for business. But the political environment is so polarized these days that top executives are often afraid to speak up against conservative dogma.

Huh? I thought Republicans were puppets of corporations. At any rate, it turns out that Toyota is, in fact, building several new factories in the U.S. as Stefan Karlsson points out here. So one factory for Canada and 3 for America and Krugman's conclusion is that Canada has the advantage?
