This, with a side of what Monochrome Tiger said.
If you WANT politics and democracy and all that to be part of the campaign, then work it in.
If you don't, then let it succeed without too much hassle, or let it fail and tell the players OOC that they cannot, within the space of the adventure, succeed.
If you do go "It's not timely to be able to do it," think a little on what kinda epilogue the Bullywugs might get-if a character is still interested in helping them after the immediate adventure, let them do so.
