Hi there, I like your website!
I teach Rhetoric at Universities, have worked in journalism and in Washington DC, and I believe your 'in' to a political website may be the on-ground connections you can make. This will take some guerilla marketing and social publicity through 'tastemakers'.
Where to start: Look at highly published bloggers on Huffington Post, Vox.com or Quartz.com. See whose voice you like.
I am excited to talk more with you. News today is built around personality of trust, let's talk more about how you can collaborate to build a political hub!
Warmly,
Arjun.
