"Generally, the smarter a person gets, the more republican they tend to lean in ideology even if they insist on remaining democrats or liberals."
I truly hope you are trolling and don't believe what you wrote. I have read some idiotic stuff on /. over the years and this one is right up towards the top.
It is more like: "Generally, the older a person gets the more conservative they tend to lean..." The older you get the more you have thus you have more to lose. I tend to think it is more like "Generally, the more intelligent a person gets the more centrist they tend to lean..." Key being intelligence (contextual application of data) vs smart (memorization of data) and realizing that voters are a diverse group with diverse wants, needs, etc etc so there is rarely a single right answer to complex issues.
Having said that, thinking of politicians as "democrat" or "republican" is a trap. If you pay attention you will see they are more alike than they are different. I tend to think of them as two different marketing campaigns for the same organization.
