In truth, Lewandowski has never operated the way that a traditional campaign manager at the presidential level would. Typically, the campaign manager spends the vast majority of his or her time in the campaign headquarters - serving as the conductor of the orchestra rather than, say, the first violin.
That's a recognition of how many moving parts there are in any presidential race - much less one like this that seems to be headed toward the first brokered convention in modern political history.
Lewandowski, by contrast, has been part of Trump's travelling retinue for the entirety of this campaign. His role has always felt more like the job description of a candidate's body man - serve as a confidant and travelling companion to the principal - than of a campaign manager.
It is impossible to simultaneously oversee the deep-in-the-weeds effort of delegate assigning, the on-the-ground organising in future caucuses and primaries, the outreach to the political establishment and 1000 other things while also serving as the sounding board on the road for the candidate.
There's a reason that Matt Rhoades managed Mitt Romney's 2012 presidential campaign from Boston while Bob White, a longtime Romney friend, and Stuart Stevens, a GOP strategist, served as the road crew for the governor. No one can do all of those jobs at once. Or, more accurately, no one can do all of those jobs well.
This move to Manafort seems to be a recognition by Trump that after losing the Wisconsin primary and seeing himself outmanoeuvred in the delegate selection processes in places like North Dakota and Louisiana, it was time to put someone in charge who had been through all this before. It strikes me as an honest analysis of what his senior people - especially Lewandowski - are good at and, by extension, what they aren't good at.
It also looks to be the takeover - or, at least the partial takeover - of professional political types within Trumpworld.
Manafort joins people like Rick Reed and Ed Brookover, longtime GOP strategists, as non-original Trumpians now in the campaign's inner circle.
The question, as always with Trump, is how much he listens to anyone not named Donald J Trump. Who he puts in charge of the campaign only matters if he is willing to actually take that person's advice. Whether Manafort can have Trump's ear is a question that still needs answering.
