DACA can drastically change the political sphere
While almost all DACA recipients themselves cannot vote as Dreamers, many of them will eventually become citizens in the future and will be able to vote in elections. DACA laws have been changing frequently. Generally, DACA provides a pathway to citizenship for more than 2.5 million immigrants. Increasing the number of voters coming from DACA can affect the results of elections. The government gives DACA status to children of unlawful presence which encourages more illegal immigration. More immigration leads to more future American citizens who can vote and may influence the outcome of elections. Additionally, some DACA recipients can vote in some large cities like Chicago and San Francisco. The current votes of DACA recipients, the future votes of US citizens coming from DACA, and the increase in illegal immigration due to DACA greatly changes the political sphere and can change election results. 
Voting represents a major part of American democracy and reflects the choices of the people in the United States. Over 72% of Americans support DACA to give protection for immigrants against deportation. The largest group of voters now is young people, and many of them support DACA. As long as people are legally registered to vote obeying federal and state laws, there is no issue in the changes of the political sphere. The US population is dynamic and continues to change and voting should represent the current US population at every election.
