Political Art vs. Art Made Politically

So, after thinking about it some more and having some of my confusion cleared up in class, this is what I think the distinction is:

Political Art
- artwork which contains political undertones
- artists is referring to something in the content
- the message is in the content

Art Made Politically
- made outside the art market
- the message is in the form as well as the content

So some examples of political art I found are:

1. F*** You (Very Much) by Lily Allen

This is a song by Lily Allen about George Bush. It's a critique on him, as a person, and some of his policies. For example:
"Look inside, look inside your tiny mind Then look a bit harder 'Cause we're so uninspired, so sick and tired Of all the hatred you harbor So you say it's not okay to be gay Well, I think you're just evil You're just some racist who can't tie my laces Your point of view is medieval"

There's also a website that features a lot of political art and they say, "We believe in freedom of expression, including expression that might make you, or us, uncomfortable."
They all address problems with the US government and the war. I've posted some of the ones that caught my eye.
