There are now an estimated 23 million immigrants in the United States that are eligible to vote.

On Super Tuesday, more than half of them will have voted in the four most populous states: California, New York, Texas and Florida.

Immigrant voters have grown steadily in the past two decades, up 93% since 2000, according to Pew Research.

In the 2020 presidential election, one and ten eligible voters will be immigrants.

But being eligible to vote is one thing, registering and showing up at the polls is another.

Historically, the voter turnout rates for immigrant eligible voters has lagged U.S.-born voters, according to Pew.

But this year, some say the enthusiasm of immigrant voters has grown.

Many immigrant first time voters came to cast their ballots, said Maritza Zermeno, the precinct chair at a polling station in Fairfax County, Virginia.
