Final answer:
Metropolitan cities generally lead to higher voter turnout due to increased accessibility to polling places and more diverse voter demographics. However, factors such as long commutes and new voter ID laws can pose barriers that impact turnout.
Step-by-step explanation:
Metropolitan cities affect voting in major elections in various ways. One notable impact is that they can lead to higher voter turnout due to increased accessibility to polling places. Cities often provide more polling locations and better transportation options, which can lower the cost in time of voting and the transportation costs.
It is also essential to consider the institutional factors that impact voter turnout. Easier registration, more extended polling hours, and accessibility can facilitate higher engagement. However, new laws have sometimes added barriers to voting, like stricter ID laws and the proof of citizenship requirements, which may decrease turnout particularly among certain demographic groups.
