Two years ago, I wrote about what Kara Eastman’s victory in the Democratic primary for Nebraska’s 2nd Congressional District meant for the party. Eastman’s narrow win, without the support of the Democratic Congressional Campaign Committee (DCCC), was “stunning,” I said. “If there is to be a Democratic wave, it is outside insurgents such as Eastman who will drive it.”
