To glance at Donald Trump’s feed on his Truth Social platform this weekend, you would be forgiven for thinking all was well in Maga world.

The soon-to-be 47th president has been serving up his normal diet of provocation and self-promotion: railing against the Democrats’ alleged financing of celebrity endorsements, for example; reposting a dig at Joe Biden’s fitness for office; plugging a Newsmax interview with his wife Melania. All fairly standard Trumpian fare.

Zoom out to the wider Republican sphere, however, and the picture is somewhat different, with a row taking place so vocal and bitter that it threatens to rip apart the coalition that swept Mr Trump to power only eight weeks ago.

The question of visas for skilled tech workers may seem relatively arcane as a political issue.

However, over the past few days it has brutally exposed a fissure at the heart of contemporary Trumpism.
