Lead Trump campaign operatives are hoping Biden stays, believing polls showing their best options are among young minority voters, slowly confronting Trump vulnerabilities, & refocusing away from broad voter contact toward low propensity Trump voters:

Polarization likely means polls stay within a modest range. But also cuts the other way. If this degree of negative media coverage, visible faltering, & internal dissent only moves polls 2-3 points, what would be required to move them the ~5 points toward Biden that he now needs?

How Think Tanks Drive Polarization & Policy

Project 2025 is just the latest step in the long rise of partisan think tanks; they helped polarize Congress, replacing non-partisan expertise

precincts where Trump was popular experienced large relative declines in turnout in the 2020 Georgia runoff, possibly due to his allegations of electoral fraud

Americans support a wide range of redistributive policy packages—as long as the wealthy are footing the bill or the costs are hidden. But when taxes are born by larger groups, support declines. Republican opinions are divided by class

Even if Dems do well in 2024, they are unlikely to have a trifecta with a committed majority willing to play reform hardball for many years. The constraints established by the Supreme Court are likely to stand, limiting liberal policymaking & empowering Republican presidents.

Even if Trump was on pace to win pre-debate (& even if another Dem would have done ~same), the accepted narrative of a Trump win is likely to be that Dems blew it by renominating Biden. Voters might not remember the debate, but it will stick out as an off ramp Dems didn't take.

The debate & after-debate coverage are also likely to further diminish interest in a campaign that was already depressing & uninteresting to many Americans, possibly further reducing viewership for the conventions & any 2nd debate.

The legal & policy wins of the corporate & conservative establishment do not make the cultural & populist Republican turn a farce, but they should temper claims that Trumpism fundamentally transformed conservative goals. Mutual accommodation is made easier by close 2-party polarized competition

Anti-corporate rhetorical moves of Republicans under Trump are real, enabled by changes in business & among voters. They have sometimes been backed up with real bills/policy. But traditional tax & regulatory party agendas, often with more $ implications, are ~intact & polarizing.

Conservative policy advances (rather than just stopping liberal expansions) are rare. The congressional record under Trump was quite mixed, with a big conservative win limited to taxes, & the administrative record included lots of policy failures. But court control has been very impactful.

The conservative legal movement was part of the Republican establishment brought in earliest to Trump. It made peace near completely & has been rewarded with quick generational advances, not just for social activists but also for economic conservatives & their own long-term power

With conservative control of Supreme Court projected for decades & no reason to expect Dem Senate dominance soon, will be substantial constraints on liberal policymaking even under Dem presidents. Constrained Biden agenda & Trump COVID agenda may be liberal high points for years

Despite everything, Twitter is still where narratives congeal across media, activists, & politicos, quickly & with the ability to influence other media. Last night, it was within minutes of the debate start. Bluesky & threads are not close to real-time alternatives to its role.

Weakening of administrative deference & the major questions doctrine will likely combine to severely limit unilateral policy actions of (especially Democratic) presidents, setting the threat & expectation that any significant liberal admin policy change will be overturned

Debates can matter, usually by stimulating clear media narrative that even those who did not watch it hear clearly. Liberal media & commentariat are not at all mirror images of conservative side, including having more ties to neutrality & self-criticism Candidate traits matter

Public opinion moved thermostatically in favor of immigration under Trump & against it under Biden. But opinions on race moved leftward under Trump but held steady under Biden, in part because salience of race has declined dramatically since 2020

Idea is to use advance of wind & solar in Texas to cue either that market-based policies provide solutions OR that conservative actors & groups bring solutions. Ideally, we'd also have a negative partisanship treatment where Dems are hypocrites while Reps are providing advances

I would like to come up with a survey experiment to test "solution aversion" on climate change views but compare it against a "coalition aversion" alternative, where Americans change views due to the political side & affiliated groups associated with belief in a large problem.

Biden has had a massive advantage in swing state advertising so far, though it has not translated to increased polling support. His new ads more directly attack Trump's conviction, but it is unclear whether they (or any ads) are working.
