Current political branding

As Anarchism is a social/political movement I thought it would be important to research what is most popular in political branding.
From what I can see flat design is very popular amongst political campaigns. Also the colour palate is limited to around 3 colours. The fact that this style of design is popular within political campaigns I can assume that it's very effective in communicating ideas and gaining support.

For my brand to be relevant within the political spectrum I need to consider this style of branding.
