It is an anachronism to say that Marius was in the "Republican democratic" party in Rome. There were no political parties, only factions, and none of them were democratic.
[edit] fact or fantasy?
If this is not pure fantasy, it needs to be supported: "His cousin Caesar always thought highly of him and his father (except perhaps when the elder Marius forced a socially constricting priesthood on young Caesar, fruitlessly trying to prevent Caesar's eventual outstripping of his own fame)." Caesar's nomination as flamen is perplexing, but it's more likely that Sulla was the one trying to simultaneously honor and render him politically impotent with the appointment; see Ronald T.
