Just found this.  Back in 2016, this economist constantly reweighted the 2016 LAT/USC poll based on the American Community Survey and other demographic data.  Not only did his "reweighted" version come within 0.2% of the final margin on Election Day 2018 (his final margin was Hillary +1.9, the actual was Hillary +2.1), but his estimations basically worked perfectly as a leading indicator of the RCP + other poll aggregates that was ahead of them by a week or a little less.

I went ahead and tweeted the gist to him. His response:

Yeah, I mean considering the sample is now literally ALL of the RNC and we've seen no bump whatsoever, so...

Just bumping this b/c people really out here yelling tightening when this thing has been steady for over a week now, and the polling period is all including the RNC.

The actual numbers are bs but they're very good at showing daily trends.

+10% using the traditional as opposed to the probabilistic sample, but the trend has been steady in both results.

I think the stuff I posted earlier shows that this pollster is very good and useful for accurately showing movement in the race-- they just really really sucked at weighting their results properly in 2016.  They did a good job in 2012 (apparently the RAND American Life panel from that year was run by the same people) so hopefully they've fixed whatever was wrong last time, but who knows.

This is where it was before the DNC. Afterwards it went Biden +15 and now after the RNC it returned to status quo ante.

Probabilistic: Biden 51, Trump 43

Pretty much settling into the same +8-ish everyone is seeing

Nice, to see that blue avatars whom thought Trump was coming back, don't get their hopes up, any longer, Trump is doomed

So this poll shows the DNC and RNC bounces as basically exactly equal and offsetting (~4-5% for each), and the horserace at pretty much right where it was before the conventions.
