(CNN) Election Day is still 16 days away and more than 27 million ballots have already been cast, according to a survey of election officials by CNN, Edison Research, and Catalist.
Voters in the 45 states and the District of Columbia that make pre-Election Day data available are already setting records. The ballots cast so far represent almost 20% of the more than 136 million total ballots cast in the 2016 presidential election.
Some of the voter information comes from Catalist, a company that provides data, analytics and other services to Democrats, academics and nonprofit issue-advocacy organizations and is giving new insights into who is voting before November.
Early in-person voters in Georgia have already cast more than 1,450,000 ballots as of Sunday afternoon. That's up 152% from 2016 when 578,147 ballots were cast during the same period.
As of Friday, ballots are available in all 50 states and DC. In-person voting will kick off in a slate of critical swing states in the coming days.
Nevada opened early in-person voting on Saturday with more than 17,800 voters casting their ballots in Clark County, which houses Las Vegas.
One polling location in North Las Vegas opened two hours late due to a "hardware issue," Clark County spokesman Dan Kulin told CNN. The issue created long lines that circulated on social media, but was the only problem reported by the county as 48 in-person polling sites opened for the first day.
Attention shifts to Florida on Monday, when 52 of state's 67 counties begin early voting -- including in critical counties like Broward, Duval, Miami-Dade and Palm Beach. All counties begin early voting by October 24 at the latest.
It's pretty clear that President Donald Trump has very few paths to the White House without winning the state. It's possible, but it isn't really realistic. (Build your own electoral map here.)
So far in Florida, more than 2.4 million votes have been cast by mail, which is about 261,000 ballots shy of all the vote-by-mail ballots cast in 2016. Of the 2.4 million ballots received so far this year, 30% are from registered Republicans, 49% Democrats and 20% No Party Affiliation.
And while Democrats still outnumber Republicans in the state by about 134,000 registered voters, their lead has dropped significantly in recent years. In 2016, that gap was more than 327,000 and in 2012, it was more than 535,000.
As for registered voters by race, this time around 61.5% are White, 17.3% are Hispanic and 13.4% are Black. In 2016, the breakdown was 64.2% White, 15.7% Hispanic and 13.4% Black.
In Wisconsin, early voting begins on Tuesday. The state played a central role in Trump's victory in 2016, with rural and working class voters leading the rejection of Democrats throughout the Upper Midwest. Four years later, however, the state remains a key battleground, but one where Trump is trailing in the most recent polls.
