I could testify for this. But it really depends on how the whole electoral system works. Here in Argentina, the Electoral Committee will alocate funds for your party, should you pay the deposit and present your support in form of signatures, and that's it. Now, the big problem is, the funding is proportional to the power each party has, so in the end, a small party is always behind in votes and funding to a larger one. And larger parties benefit from having many smaller parties going at each other for a minimal share of votes. Voters fragmentation is just a bad as bipartidism. Back in the 2000's, many smaller parties united into the "Alianza", which ended up winning, yet their candidates weren't what people were expecting and it all ended badly due to mismanagement on their behalf, as well as all the inherited caos that was and will always be our government. So in the end, if the division of funding was equitative and/or limited to a few parties, say around 5, i guess there would always be a cleaner voice.
