For some more background, here’s a short academic reading list on Navalny’s politics and his movement. I’ve tried to find non-paywalled versions for all sources.
For a start, two great (though a bit older) texts on Navalny's nationalist phase. The first one is by Natalia Moen-Larsen:
https://www.tandfonline.com/doi/pdf/10.1080/21599165.2014.959662
https://www.tandfonline.com/doi/pdf/10.1080/21599165.2014.959662
The second comes from Marlene Laruelle: https://doi.org/10.1080/1060586X.2013.872453
Continuing with an analysis of Navalny’s 2013 campaign in Moscow by Regina Smyth and Ira Soboleva… https://brill.com/view/journals/rupo/1/4/article-p347_2.xml
… followed by an interpretation of his political discourse in 2011/12 by Jussi Lassila: https://www.tandfonline.com/doi/full/10.1080/09668136.2015.1120276
Now two of my own contributions. First off, a short paper with Andrei Semenov and Elena Sirotkina on his 2017/18 campaign in the regions: https://www.tandfonline.com/eprint/DAYGQXHARVDSEIPTMDWE/full?target=10.1080/14742837.2018.1483228
Second, a recent piece on the connections between Navalny’s movement and the For Fair Elections protests of 2011/12: https://www.tandfonline.com/eprint/CMDBM6XCHD3RRN2MNMPQ/full?target=10.1080/1060586X.2020.1750275
Finally, two works on his “Smart Voting” strategy. First, a short piece I wrote for the Russian Analytical Digest shortly after the 2019 Moscow municipal elections:

https://css.ethz.ch/content/dam/ethz/special-interest/gess/cis/center-for-securities-studies/pdfs/RAD239.pdf
Second, and a very recent piece by Mikhail Turchenko and Grigoriy Golosov that finds a relatively large effect of “Smart Voting” in the St. Petersburg municipal elections: https://doi.org/10.1080/1060586X.2020.1796386
Let's hope for the best. And please feel free to add more stuff!
