Lower turnout at polls isn't apathy, it is dissatisfaction with the choices

In the US, it is tradition that if you are dissatisfied with government, you don't vote, as noted by the low 37% turnout in this month's election. That 63% of no shows don't like there choices, so they don't bother making any choice, instead of making a difference choice (Non-democratic/republican). Unfortunately, the Constitution doesn't account for non-voting as non-support for government.   I think we need a minimum voter turnout (quorum) in order to count the voting results as valid.  Let's say, 75%.  You want to know how hard politicians would work for your vote in that case?  A lot!  They might listen to the average person and take action to support their needs.  Imagine that!
