The following pairs of items are different things:

• Apple, Orange
• Public Servants, Politicians

I don’t need to illustrate the first difference, but the second can be demonstrated by successive tweets I received from DUQ:

• Public Servents: Lawmakers and Power Companies Debate Rate Caps
• Politicians: Mayors Gather to DISCUSS Solar Energy

Ladies and Gentlemen, we have a politician and not a public servant as mayor of the city. Perhaps it is time to reconsider.

Also, DUQ has good tweets, you might consider them.
