Texas redraw would give Republicans more of a national advantage in districting, but from a low point in their advantage relative to the last few decades (though it may matter more now that fewer candidates substantially outperform their party)

Communities with colleges exhibit higher levels of civic engagement and greater social trust today, relative to โ€œrunner-upโ€ locations without colleges that were considered long ago. These counties are also more politically liberal, especially since 2000

U.S. Public Trust in Higher Ed Rises From Recent Low More Americans say they are confident in higher education now than a year ago, the first increase Gallup has measured in the decade-old trend.

Confidence in higher education is rising again (likely thermostatically in response to attacks), but with remaining concern more concentrated on politics & less on costs

1 view (DK yet how true) is that Obama with Congress used surplus to successfully relax repayment with limited Rep rollback & ~consensus on degrees for jobs. Biden did massive forgiveness without Congress, which was mostly undone & stimulated Rep retrenchment of Obama reforms

What is the best history of the student loan limits that ended up in the reconciliation bill? I would like to know how much they were developed in response to Biden's expansion of forgiveness & changes in payback terms & how much they slowly built independently?

One AI dystopia (that we might say is already in progress with conventional software) is that we can achieve grand-scale standardization & rule-setting & that many remaining human jobs are finding ways around these systems, especially through the layered kludges of the past.

Many assume that bureaucracies function well by optimizing & then standardizing procedures. But close looks usually reveal they function well when goal-oriented implementers close to the ground know & practice loopholes, overrides, & fast-track alternatives.

The Senate Passed a Federal Voucher Program. What's in It? The measure would create a national program funding private school tuition through tax credits, though states would have to opt in.

The revised voucher provision in reconciliation still opens an option for Dems to copy. Rather than appropriate $ for alternative energy, health care, or social services, they can just give 100% tax credits for individuals to give to charities to do it

Pew & Catalist disagree about the education divide by race, not only in 2024 but in prior elections. Pew shows earlier divides, so not as much continuation of the trend. Catalist shows extension to minority groups in 2024 & a slower build.

Biden & Trump immigration changes seem to have reduced border flows. To what extent will increased interior enforcement, including showy raids, lead to more outmigration (self-deportation) of those already here, especially with larger ICE budgets coming? Any evidence so far?

Reducing the insured population & adding a rural hospital bailout is quite the kludge. Some budget wonks advocated many of the Medicaid cuts (provider tax limits & immigration & work enforcement). But was any wonk advocating this combo as a fix for US health care before the bill?

Some useful details in replies. But institutional lobbying on bills likely to pass tries to tone down negative provisions, work for least-bad options, & win exemptions. That's what they did here. It's more a failure of folk theories of lobbying (bills pass because lobbyists) than lobbying literature

Don't think "Dems should have strong-armed Manchinema more" is an analogous lesson here. Republican leaders made deals with individual moderate holdouts when they had to (& lost a couple). Most of the successful strong-arming was on right-wingers to go along with the deals.
