Yes it's pure liberalism. The "team of rivals" only worked because Lincoln held them together and they (the rivals) had a mutual enemy in the confederacy. It's basically that centrist meme about planes with both wings on one side of the fuselage "YoU nEeD bOTh WiNgS tO fLy!" horseshit. Meme level analysis and solution. Shallow as some pithy Reagan retort.
