NRSC plans to take sides in primaries — but is this really such a good idea?

The National Republican Senatorial Committee is going back to a policy of taking sides in primaries, we report this morning:

Senate Republicans are signaling they’re willing to box out weak GOP candidates in the 2024 primaries following a lackluster 2022 performance that ended with their minority shrinking in the upper chamber.

The example mentioned here is Rep. Jim Banks (R-IN), and I imagine that the committee’s intervention will work just fine in his case. In fact, it already has helped, prompting another would-be candidate to drop out and clear the field.
