This bit of the article and the Washington Post report it links to really demonstrates our problem concisely

[Jack Smith] carried out his investigation and drafted Trump’s indictment at a remarkably swift pace—Attorney General Merrick Garland appointed him only last November—even as he was also overseeing the probe into Trump’s mishandling of sensitive federal documents at his Mar-a-Lago compound. So while it is indeed a relief to ponder the prospect that Trump may face actual consequences for his subversion of the Constitution and his governing oath, it’s also vital to ask ourselves just why and how a case this important for the rescue of whatever remains of our democracy, and founded on a great deal of already available public information, aroused such belated and half-hearted interest from the justice system.

Alas, the same basic profile of a sclerotic and unresponsive status quo holds for the federal enforcement of election law, as the institutional background behind Smith’s January 6 probe makes all too clear. From the outset of his tenure atop the Justice Department, Attorney General Merrick Garland evinced little interest in mounting any such investigation, fearing that the GOP’s permanently aggrieved MAGA base would view it as a weaponized, partisan effort to hound Trump into political irrelevance. As a blockbuster report by The Washington Post’s Carol D. Leonnig and Aaron C. Davis revealed this June, for a full year after the insurrection, Garland’s team looking into January 6 “consisted of just four prosecutors working with agents with the U.S. Postal Inspection Service and the National Archives and Records Administration.” Garland also shunned any wider probe into Trump’s coterie of political shills and hack-legal advisers building the case for him to gin up a bogus roster of alternate electors from swing states to throw Congress’s January 6 certification of results into chaos. Those sycophants and grifters are now unnamed co-conspirators in Smith’s indictment, and will be subject to future legal proceedings. In the end, Garland didn’t mount an investigation into the electors scheme until 15 months after the failed coup attempt.
