Politicians like to talk in abstractions.

Come to think of it, they like to argue and obfuscate in abstractions, as well. They campaign in abstractions and make abstract pledges until those abstractions turn into something tangible, like a subprime lending crisis or a downgrade from a particular private rating agency.
