Conservative books sell better than liberal books. Why?

[JI7]

82. Probably the Same Reason Right Wing Radio Does Well

even based on DU there are many who don't watch or listen to "liberal" media.

but if you go on something like freerepublic it seems like every member there listens and watches all the rush, fox news and other crap.

i prefer to read a good story in itself than some book telling me how bad conservatives are. there are some like krugman i like to read because i learn more about the subject itself.

but someone bought me some Bush bashing book once which i never read just because i already know how bad he is. there are other things i prefer to read.

also what is considered liberal ? i liked nickel and dimed by ehrenreich . i guess i prefer political books of that type.

many books i like have a political message to it but they are probably not considered political .
