It might be a better idea to write the
reply in plain-text utf-8 or at least
Western or Eastern-European ISO euro
encoding instead of us-ascii (maybe
KOI8, ¯\_(ツ)_/¯) ... something in your
email got string-replaced by "?????" and
also "«" got replaced by "?".
Please research using Thunderbird, Claws
mail, or some other sane e-mail client;
they are great, I promise.

Good!

Yes, some type of header element at
least, in-between the various tables,
everything children of the div in the
element tree.

Yes, doing that for the political office
is also possible, but the party is
inside the table's caption tag, which
end up as the name of the table in the
XML::readHTMLTable list ...

Why is that, please explain.

No, there is not, AFAIK. Please, if
anyone else knows, please say so *echoes

Such a great hack! IMHO, this is much
more flexible than using
xml2::read_html, rvest::read_table,
dplyr::mutate like here[1]
