I'm not sure what your prompt is, but I think a better introduction would help.

I'd be wary about making the claim that voter turnout has decreased in the recent decades - by mere percentages it HAS, but 18-20 year olds got the right to vote in the early 70's, and after that dropped it enormously, and it's stayed consistent since then. Going by merely presidential elections, which is what most people vote on, we were in the low-60's in '60, '64, and '68. The '72 election between Nixon and McGovern featured 55%, approximately. The '04 election had 56%. And most people expect this election to feature an enormous voter turnout, maybe even 60%.
