"And no we cant move away from them they moved in with us a week before 9/11 due to health problems and this has been life with the pod people ever since then."
The best thing to do is just smile and ignore them, I had my father living with me for some months until his death in 1995 and I remember his saying one day that the biggest mistake the American people ever made was electing Ronald Reagan and then they turned around and elected him again. I knew if I pointed out to him that I felt exactly the same way about Bill Clinton he would have gone into a sulk with me so I just pretended not to hear him. I had driven him nuts all my life by supporting conservatism so I figured I might as well let that go by. My father was very smart about some things but when it came to the government he was always childlike and thought whatever the Feds wanted to do was just wonderful.
This is how my liberal relatives are too. They live their lives as hard-boiled conservatives - then put away all they know when they form their opinions about things on a national scale they are not directly involved in - and do not see the direct results of. It helps to point out their own behavior and opinions about how they live their lives - and how different they are from their opinions about national affairs. Principles are universal - on big stages and small.
