There are obvious variations in support for policies among Democrats.
By calling myself a moderate democrat I'm trying to distinguish myself from the people who call themselves progressives. If anyone has another term for this, then please share.
I laid out what my vision of moderation is relative to what I hear from progressives. For example, I think that incremental changes in a positive direction over many years is preferable to a 'throw out the entire system and remake it' approach that is advocated by progressives.
I'm not making up language; it's a distinction that progressives will tell you certainly exists. It's in many polls. Here is a poll trying to show an distinction.
I put myself in the light blue section. I agree with most all of the Democratic Party platform positions, however my approach to implementing them is more moderate than progressive. Additionally, I would not go as far as some progressives on some of the issues.
