There is somewhat of an intellectual void in Republican leadership over the past 20 years. Occasionally that void creates space for a uniquely good idea that doesn’t align too well with ideology. When the Democrats are in charge, there are plenty of mainstream Democratic ideas to fill up the agenda, so nothing too unusual happens.
The low ideological alignment also explains why these ideas are underrated later, because they have no deep well of partisans to promote their successes.
That is from Kevin.
