A lot of the elistist academics and latte liberals don't want to associate with the inner city minorities even if they vote for the same party.
This does haves some truth to it.
The latte liberals supply more dollars than votes. The minorities supply more votes than dollars.
Both see the GOP as a threat to them.
Same divide is just as (if not more) true on the other side.
Big business/economic conservatives supply more dollars than votes. Evangelicals/social conservatives supply more votes than dollars. Both see the Democratic Party as a threat.
