My neighbors are 2 newly-weds that I found out are polar oppposites when it comes to politices. Whenever a political subject comes up and the conservative point is made, the wife frosts over (liberal democrat). I see nothing but trouble in the future for these two...
My brother is a conservative and his wife is a hard-core lefty. These two have had so many problems in the nearly 5 years they have been married everyone is amazed they are still together.
Sounds like My Sister (Republican) and Brother-out-Law (Dim) but somehow it works.
