Case 1: Yacht Club Argentino, which was ISAF MNA at the time (as US Sailing is ISAF MNA for the US), had a fight over the MNA status with the Argentinean Sailing Federation, which is the official branch of the country's Olympic Committee. Both asked for ISAF intervention, etc. ISAF never took party or intervened, just regretted the situation. Things were settled after years (decades?) of political fights, without any action from ISAF.

Case 2: same thing in Paraguay, no action from ISAF, took about three years to settle.

Conclusion: it would be a surprise if ISAF intervenes or takes any action in connection to a country's internal affair.

Still, the suggested actions would help in proportion to the publicity obtained, so it would be more useful to communicate the "votes of no confidence" with copy to the press.
