  bibo_abstract:
  - We propose an elementary tropical analogue of a reductive group that combines
    the datum of a Weyl group and the tropicalization of a fixed maximal torus. For
    the classical groups, as well as $G_2$, these tropical reductive groups admit
    descriptions as tropical matrix groups that resemble their classical counterparts.
    Employing this perspective, we introduce tropical principal bundles on metric
    graphs and study their explicit presentations as pushforwards of line bundles
    along covers with symmetries and extra data. Our main result identifies the essential
    skeleton of the moduli space of semistable principal bundles on a Tate curve with
    its tropical analogue.@eng
