Essentially mobilization of society by making people feel deeply emotionally connected to a cause. Successful politicians have an intuitive feel for what will trigger a loss in elections and will change course those that don't are wiped away irrespective of wealth lobbying. This has happened and continues to happen many many times in many many countries but it usually does take a group of motivated people (and another group of people who have faith in them to underwrite their living expenses) to essentially focus on the cause to the exclusion of everything else. It is remarkable if you go through history just how much has been achieved through persistent (years or decades) of the above types of efforts with very little money. The reason ordinary political campaigns require a lot of wealth is because they're run by people and on issues which people running them don't really care about much.
