No.
The Economist ran an article highly supportive of the hearings, The January 6th committee has hobbled Donald Trump, but concedes that its impact on the faithful has been fairly limited.
America should count itself lucky that Donald Trump tried so hard to overturn the election of 2020. That is the biggest obstacle—though far from an insurmountable one—standing between him and a return to power.
But do not imagine that Mr Trump is fading away. “Half of gop voters ready to leave Trump behind, poll finds”, read a recent headline in the New York Times about a survey it conducted with Siena College. It is wiser to emphasise the darker view, that the glass remains half empty. The intense loyalty to Mr Trump of half the Republican base means that, the more Republican candidates choose to run, splitting his opposition, the better it will be for him. Betting markets are placing a higher probability on Mr Trump’s being the next Republican presidential nominee than on Mr Biden’s being the next Democratic one.
In a sign that the committee’s work is not reaching, or at least not persuading, many Americans, the same poll found that fully three-quarters of Republican primary voters believe that on January 6th Mr Trump was “just exercising his right to contest the election”. If Mr Trump reached the general-election campaign, he would be able to count on the polarisation of American politics to draw the party together behind him, as in 2016.
Basically, if you're a Democrat, he sucked, nothing new. If you're a Republican, it's being ignored mostly so far. Fox News, for example is providing limited coverage.
The poll they are referring to, by Siena College & New York Times, ran July 5-7th, so it got the reactions to hearings up to installment #6, I believe.
A majority of voters, 55%, say Trump threatened American democracy through his actions following the 2020 elections, compared to 39% who say he was just exercising his right to contest the election.
“Not surprisingly, Democrats and Republicans regard Trump’s actions in the aftermath of the 2020 election very differently. While 92% of Democrats think Trump threatened democracy, 76% of Republicans said he was just exercising his right to contest the election. Independents side with Democrats, 56-37%, in saying Trump threatened democracy,” Levy said.
I suspect however that this, along with the whole Jan 6th riot, will be extremely fertile terrain for attack ads in 2024.
