The U.S. presidential election is now just eleven months away.
President Trump is virtually certain to be the nominee for his Republican Party.
But for the Democrats, there are 14 candidates vying for the nomination.
In their race, there's a lot at stake at each stage of the race in terms of momentum and attention from donors and the news media.
The first results will come next month in the state of Iowa.
Iowans will vote for the Democrat of their choice, and based on their votes, the state will send delegates to the Democratic National Convention later this year to decide the nominee.
Other states have a similar process.
The second big vote will be on Super Tuesday, when more than a dozen states hold primaries and caucuses.
That day will determine around 40 percent of the Democratic delegates.
On the Democratic side, the frontrunners are former Vice President Joe Biden, Senators Bernie Sanders and Elizabeth Warren, Mayor Pete Buttigieg of South Bend, Indiana and former New York City Mayor Michael Bloomberg.
In a recent poll by Reuters, Biden, Sanders and Warren were the top three.
However, experts say that among the Democrats, there's no game-changer.
"Whether or not that candidate is a truly once in a generation inspirational charismatic candidate like Barack Obama in 2008. And thus far, I don't see any of the Democratic front runners fitting that model. That could change of course if someone actually becomes the nominee it could be different."
Meanwhile, President Trump has been impeached by the Democrat-controlled House and is waiting for the Republican-held Senate to hold a trial.
The Democrats are refusing to send the articles of impeachment to the Senate, saying a trial there would be unfair.
On its face, impeachment would spell the end for most politicians, but for Trump, pundits say it could make his support even stronger.
Experts say one point of vulnerability for Trump could be his record of canceling or substantially weakening many climate and environmental regulations, which is an issue that energizes many Democrats.
"Climate change has been steadily moving up as an important issue for the voters, which was kind of non existent in 2016. But it will be an issue in 2020 and Trump has turned back the clock on efforts to combat catastrophic climate change exposing Americans and people all over the world."
Wall Street is also watching the race closely.
Investors have done well under President Trump.
They're wary that a Sanders or Warren presidency could mean a radical shift in the U.S. economic model through taxes on wealth and spending.
