"people more readily obey a system which purports to heed their input". Sounds like democracy.
There are many indirect effects that may help, people feeling represented is one of them. But they are near to irrelevant when compared to that direct one.
Forget worrying about single votes: even having most of the votes isn't necessarily enough to influence things! (Referring to the 2000 and 2016 presidential elections, and to the concept of gerrymandering.)
