Wow, the OP is totally confused about so many things.
1. Not all Christians are conservative. Many denominations are pretty liberal.
2. European Conservatism and American Conservatism are light-years apart ideologically.
3. European Christians and American Christians are light-years apart theologically.
Anyone who's lived on both continents knows that the OP's proposition is completely ridiculous. I can see the minority of Evangelical sects that have popped up here and there in Europe, mostly the UK, considering an alliance with their American brothers and sisters in faith, but other than that, forget it.
