I'm very engrossed in European politics and I've noticed the very strong resemblences of some Republicans to far-right parties there. People like Tom Tancredo sound like Austria's Jorg Haider of and the FPO (Freedom Party) and France's Jean Marie Le Pen and his FN (National Front) with their anti-immigrant rhetoric. It's scary to see that politicians here have embraced some of the same ideals of these parties which are considered way out of the mainstream in their respective countries. Unlike in those countries, the far-right has masked themselves as mainstream to the American people, hiding their views. Also, in the example of the BNP (British National Party) they play of single issues to sway some voters who don't know their true intent. The BNP has won council seats in England playing on immigration issues, almost the same way Republicans use social issues to get votes. On the values and morals aspect, The Republicans also have mirrored in some aspects the Turkish Welfare Party, which said it wanted to bring Islamic morals and values to Turkey. That didn't set right with Turkey's secular constitiution and the party was eventually banned. The Republicans are bringing ideas that are not accepted in the Western World, but have been incognito about them until now when it's unraveling.
These are links to read about these people and their parties.
