On several occasions, since my brief dalliance with a company and website called American Certified - which, alas, is no longer in business - I have cited a group I first ran across around that timeframe called the Alliance for American Manufacturing (AAM.) I have also pointed out that their perspective comes from their backing, as it is a conglomeration mainly composed of unionized steel manufacturers - so I always assumed they were more in line with the Democratic Party than the Republicans, which traditionally have been more in favor of free trade rather than protectionism.
