On the national level, yes. I know Dims locally (a rural town in Illinois) who aren't that liberal or vocal. On the other hand, those connected with our community college are 'out there'. One of 'those' we used to church with (before changing affiliation) gave money to the Dean campaign. Then, her husband wanted my wife and I to post a campaign sign for him (the husband) on our lawn when he ran for city office. We politely turned him down (as we did all other similar inquiries). He hasn't talked to us since.
Get the picture?
We've had that happen to us: libs who end relationship as soon as they find out we are conservative. How tolerant is that? I find it sad.
