The answer will help you. The main argument of the United States census source, is that the people vote more frequently in presidential elections than congressional elections. The demographic with the most frequent voters is white 65 and above men with high levels of education, and income. However, the voting pool has been slowly started to become as a more diverse. The making the point that voting might not be totally taken advantage of by all the diversities of citizens therefore might not be representative of our all of our citizen's interests. As well the Census makes the point that young Americans are not to voting nearly as much compared to the amount of older Americans that are.
Opposition increased over time because american citizens had kept seeing the results of the war. For example, like increased funding, many deaths, and lost a lot of battles. As the war continued and the US was not progressing any in defeating North Vietnamese forces, Americans began to view the fighting as pointless due to all the consequences. I believe it was justified, because the outcomes could have been avoided if peace with Vietnam was settled earlier or if the US didn't even get involved.
