The 2020 presidential race is finally drawing closer to ballots being cast for the candidates in primary contests across the US.
As Democratic presidential candidates prepare for vital early primaries, they'll also participate in six more televised debates. The Democratic nominee will then participate in presidential debates this fall.
Republican parties in several states have cancelled their party primaries, presuming Donald Trump will be the incumbent nominee on the ballot, though he has attracted several challengers.
Here's a schedule of key election events in 2020.
Five candidates have qualified for the seventh Democratic debate, which will be hosted by CNN and The Des Moines Register at Drake University in Des Moines, Iowa. On the stage will be Joe Biden, Pete Buttigieg, Amy Klobuchar, Bernie Sanders and Elizabeth Warren. The debate will be moderated by CNN's Wolf Blitzer and Abby Phillip and The Des Moines Register's Brianne Pfannenstiel. It airs at 9pm EST.
The Iowa caucus will capture the first votes cast in the Democratic primary race, leading to a lot of speculation for the candidates' futures as state primaries following in the coming weeks, and as the campaigns — and donors — strategise ahead of the election's crucial next few months.
ABC, WMUR and Apple News at St. Anselm College in Manchester, New Hampshire host the eighth Democratic primary debate.
