If young voters start a new trend of turning out to vote in huge numbers, how might that affect the policies candidates focus on in the future? How might it
shape the kinds of laws that are put in place?

change the whole scenario of political system in the country.

Explanation:

The turnout of young voters have always been low during elections. However, if young voters start a new trend of turning out to vote in huge numbers than it can possibly change the whole scenario of political system in the country.

With more than half of the population comprising of young people between the age of 18 to 30, there can certainly be a huge shift in party agenda and focus if young voters show more interest in elections. Many scholars and political scientists have found out that young voters are influenced by current issues like global warming, equality, minority rights, etc.

In order to meet these demands and needs, political parties and candidates may put more focus on implementing and promising laws that are more admissible to young people. As a result, they change thier agendas and focus to attract the most influencing demographic population.
