Interesting on hearings

As yet, there is no evidence that the work of the January 6 committee is changing many minds.
In a Quinnipiac survey released on January 12, 43% of Americans believed that Donald Trump bears “a lot” of responsibility for the attack on the Capitol. In the comparable survey released on June 22, 41% affirmed this view. And on the core issue of whether President Trump committed a “crime,” the country remains as closely divided as ever. In April, Quinnipiac found, 46% of Americans said they he had and 47% that he hadn’t. As of June 22, the split was almost identical—46% to 48%. A decision to prosecute the former president for his role in the attack would probably intensify this division.
On the other hand, the Economist/YouGov survey found, 79% of Americans now believe that Donald Trump was involved in a wide-ranging effort to overturn the results of the 2020 election, a belief shared by 49% of Republicans and an equal share of those who voted for him in 2020. At the end of the day, the former president may stand convicted in the court of public opinion if not in a court of law. The hearings could intensify the nascent sentiment within the Republican Party to find a replacement for Trump who shares his views but not his defects.
