I've worked on multiple campaigns at the local, state, and federal level. Some of my favorite ones were Chris Campbell's Indiana Senate campaign, and Solomon Rajput's 2020 Congressional Campaign. There I met some incredible people, had a lot of fun, and spent hours phonebanking, canvassing, and more. Overall, I've worked on five different campaigns.
However, it's hard to say that I still believe in the system after all of this. After watching the DNC actively work against Bernie Sanders in two different presidental runs, seeing the gerrymandering happening all over the country, seeing meaningful third party, grassroots, and unique candidates being shut down - I don't think real change comes from most political elections. At most, I think if you want change in your community, that change comes from local elections. I'm unsure if the working class is ever beneffitted from federal elections, or if it changes anything.
