Explain the term democratic overload in the context of US voting behaviour

Democratic overload refers to the idea that America is too democratic, electing 'everyone from the president to the dog catcher' you could say. The US holds national elections once every 2 years, whereby citizens also have to be involved in the primary elections, meaning that often, these national elections feel as if they go on for years. Not only this, but the US also has individual state democracy. For example 48 states have the ability to hold referenda, 26 allow citizens initiatives and 18 allow voter recall. All of this leads to even more democracy available to US citizens which can create 'voter fatigue', an issue whereby voters become apathetic and don't care enough to vote. Democratic overload is a problem because it can lead to lower voter turnout, for example even though the 2016 US presidential election was exciting, turnout still remained at 58%, which is low when compared to 2008 whereby it was at 61%. However it is important to note that US turnout is measured as a percentage of all those eligible to vote, including those who are unable to due to the fact they lack citizen status or have previously been incarcerated and therefore lost their right to vote. Therefore perhaps democratic overload is not so much of an issue due to the fact that turnout may be higher than statistics suggest.
