On Tuesday, Indiana Republican primary voters defeated state senators whose only offense was refusing to redistrict the state's congressional map mid-cycle to add Trump-friendly seats. The senators wanted to follow normal procedure. That is now a primary-able offense.

Trump backed primary challengers in eight Indiana state senate seats. He won most of them. The challengers' platform was, almost literally, 'we will redraw the map when the president asks us to.' The incumbents' position was 'the legislature decides, not the president.'

The Constitution puts redistricting authority with state legislatures (Article I, Section 4). The reason the Founders did this was to keep the federal executive out of the business of choosing congressmen. Tuesday in Indiana was a clean inversion of that design. The president picked the legislators who will pick his congressmen.

This is what the consolidation of power inside a single faction looks like in practice. Not tanks in the streets. Just a state senator who voted the wrong way getting beaten in a primary, and the next state senator learning the lesson without anyone needing to spell it out. Article I doesn't enforce itself.

How many of the new Indiana senators introduce mid-cycle redistricting bills in the next 90 days. Whether courts intervene. Whether other GOP-controlled state legislatures take the same path. Whether any congressional Republicans publicly object — and what happens to them when they do.
