Sweet home Al-Obama

Why does the Democratic party exploit our (largely uninformed) fear of free trade? This in Slate poses the question by reference to Barack ("sweet home") Obama's key note address last Tuesday:

Obama, like other speakers at this convention, complains about 'companies shipping jobs overseas' and workers 'losing their union jobs at the Maytag plant that's moving to Mexico.' At the same time, Obama holds himself out as a symbol of a diverse, welcoming America. How can Democrats be the party of diversity at home but xenophobia abroad, the party that loves Mexican-Americans but hates Maytag plants in Mexico, the party that thinks Obama's mom deserves a job more than Obama's dad does? I understand the politics of it. But what about the morals?

Anyone have the answer?
