As noted at Hot Air, by never-Trumper Allahpundit:
The survey of 1,541 U.S. adults, which was conducted from June 10-13, found that if another presidential election were held today, more registered voters say they would cast ballots for Donald Trump (44%) than for Biden (42%) — even though the House Jan. 6 committee has spent the last week linking Trump to what it called a “seditious conspiracy” to overturn the 2020 election and laying the groundwork for possible criminal prosecution…
Biden’s job approval rating has been atrophying for much of the last year, and the new survey shows that it has never been weaker. A full 56% of Americans now disapprove of the president’s performance — the highest share to date — while just 39% approve. Three weeks ago, those numbers were 53% and 42%, respectively…
How bad is it? Many more independents say Biden shouldn’t run again (76 percent) than say Trump shouldn’t (57 percent). Among Biden’s own voters in 2020, more say he shouldn’t run again than say he should, 40/37.
While there will likely be many theories floating around about how this could possibly be correct (not Biden's unpopularity - inflation and an apparent inability to convince the rogue elements in his own Party to put Democrat policy into effect account for that - but the willingness to consider Trump as a better alternative), I really think you have to consider the brokenness of the media landscape to be the major factor.
In any event, I am dubious about the polling of hypothetical contests - it's surely the kind of polling that is most likely to generate off the cuff gut reactions.
And besides, all serious people know it's already clear that Trump's position in history as a danger to democracy and the worst President who ever got into office via a cult following generated by the internet and the Murdoch media is secure. Biden, on the other hand, is likely to be seen as a victim of circumstance, pretty much like Jimmy Carter.
Nonetheless, I would prefer the polling was not like this. It doesn't inspire confidence in the future of the country...
Update: further to the title of this post:
You can only explain Republican cowardice on Trump by a lust for power replacing decency and common sense, I think? Or are there other theories out there.
