I think it's actively harmful to your own cause when you suggest corruption without any evidence. Just because politicians don't take action on an issue you think is important doesn't mean they're corrupt. It's more likely that the issue you think is important is simply not important to most voters.

Suggesting politicians are corrupt without any evidence will make that worse. If people think their politicians are corrupt they will further disengage with the political process, which will ensure there's even less pressure on politicians to take action on niche issues like this.
