Read this interesting analysis. 'The Brookings Institution, has studied, starting in the 2014 midterms, the websites of every candidate running for Congress in both parties. Our Primaries Project is working not with a sample of congressional candidates but with the entire universe of candidates. We have coded those websites for who the candidates are, where they place themselves within their party and where they stand on issues. The 1st thing we noticed is that there were many more self-identified progressives running in 2018 than in 2014 or 2016. But in spite of their large numbers, progressives did not do as well at the polls as the candidates we identified as establishment Democrats.'
