This was a really good night for Biden, undeniably. Aside from overperforming in states we knew he'd do well in, he also managed some wins in states we expected to go to Sanders. That said, when you add up the delegates (when we finally have a full count), we still have plenty of election ahead of us, and Biden will need to build on this momentum. Beyond the results, the delays and long lines in both California and Texas raised major red flags for me. These are issues that simply need to be addressed if we don't want an even more chaotic night in eight months.
