Julián Castro of Texas now jumps off the Democratic primary election ahead of the US presidential election. He announced this on Thursday via a video clip on Twitter.

The candidate has long been drawn with poor opinion figures and has had difficulty funding his campaign, while opponents in the primary elections such as Elizabeth Warren, Bernie Sanders, Joe Biden and Pete Buttigeig managed better with the opinion and attention.

The announcement comes just a month before the premiere gets underway in Iowa seriously.

Criticized the system

According to CNN, Julián Castro spent the end of his campaign criticizing how the Democrats' primary election was structured. He says the first states to vote in the primary election do not reflect the broader electorate among Democrats - and that gives some presidential candidates an advantage.

The presidential campaign lasted for exactly one year since Castro launched its campaign in January 2019.

At the time of writing, there are still 14 Democratic presidential candidates running for the primary, according to The New York Times.
