This template looks really good for the demos, but the support is really, really poor, and the site isn't optimized for the newer versions of wordpress (Gutenberg and onward).
The required plugins all require a lot of backend work on the part of your client, and if they aren't particularly tech savvy, they won't be able to get the data from forms/donations/volunteer signups/etc.
This doesn't integrate easily with any of the major electoral/political CRMs (in the US, those are NGP/Actblue/Nationbuilder/EveryAction).
Donations needing to go through paypal is a headache unto itself, and the lack of customizability on where things appear on the page is a hassle.
Finally, among all the other manifold miseries with this horrible theme, is the lack of integration with facebook events/eventbrite (or everyaction/NGP events).
Steer clear. Political clients are already pretty intense, and this will just multiply your grief severalfold.
