“Two theories may explain why the biggest shift in Trump’s favorability rating happened after Trump was charged with mishandling of classified material. For one, it is the only crime (so far) that was not known before this year. The Wall Street Journal reported on the hush money payments way back in 2018, and the events surrounding efforts to overturn the 2020 election played out mostly in public, with lots of the evidence presented in the Justice Department’s indictment initially reported by U.S. media outlets and documented in a report from the House of Representatives last year. And while there was some reporting on Trump’s legal efforts to hold onto classified material, including wall-to-wall coverage of a 2022 raid on Mar-a-Lago conducted as part of the investigation, the unsealing of Trump’s indictment for maintaining classified documents after he left the White House represented the first time the breadth of the prosecution’s allegations became clear.
That case also deals with matters of national security, which are important both to the average American and average Republican.”

“Trump’s indictments for his efforts to overturn the 2020 election, meanwhile, could have additional political costs, particularly if he wins the Republican nomination. GOP primary voters might not care about allegations of interference, but general election voters are another story: Twostudies of election results in the 2022 midterms found that the Republican candidates for the U.S. House of Representatives who received endorsements from Trump or voiced support for his election denialism performed worse than Republican House candidates who did not. In a CBS/YouGov poll conducted Aug. 2-4, a majority of adults said the indictments against Trump were “upholding the rule of law” (57 percent) and an effort to “defend democracy” (52 percent), although more than half also said the indictments and investigations were trying to stop the Trump campaign (59 percent).
And of course, these are just the indictments. Potential fallout from the trials for each series of charges (which could start as soon as January) could be even more significant. Not only will the public see an actual prosecution, Trump will also be forced to divert focus from running for president to appear in court — which could distract from his campaign.”
