The 2016 election? Both the Democratic front-runner and the nearest also-ran not only had campaign finance reform prominently in their platforms (each with a full page devoted to the issue on their websites) but also brought it up during the debates.
The primary aim of the new democratic house is to continue in the same way under the same leadership as they have for the last 30 years. They're a conservative party who mainly want the same things as Republicans, but have somehow managed to bamboozle a whole new generation into thinking they're the party of civil rights, egalitarianism, labor, etc. They're about as interested in campaign and election reform as the Republicans.
