One of the challengers to Donald Trump could be Julian Castro. He boasts of an impressive track record. The City Council of San Antonio, the nation’s seventh largest city, elected him when he was 26. He became the youngest person to get the nod at the time. Later, when he was 34, San Antonio elected him as their mayor where he served for three terms. He is a former cabinet member of Barack Obama's government and has now announced his plans to run for president.

NBC News reports his family was on the stage with him when he made the announcement in San Antonio to try for the White House in 2020.

He described himself as the “antidote” to Trump. Democrats had projected him in that role when he became the mayor of the city. His campaign slogan is catchy - "One Nation. One Destiny".

Ancestral roots of Julian Castro are in Mexico

His grandmother migrated from Mexico nearly 100 years ago. It is the country that Donald Trump loves to hate and during his 2015 presidential candidacy announcement, he said Mexico was sending drug traffickers and criminals to the US. That is why he made a campaign promise to construct a permanent US-Mexico border wall to "Make America Safe Again." If Julian Castro takes over the White House, the strategy might change.

Castro has drawn up an action plan.

If elected, his first work will be to bring the United States back to the Paris Climate Accord. Trump had withdrawn from the accord, which is an international agreement on climate change. Its implementation is necessary to maintain the balance of nature. Castro is also worried about the fate of Puerto Rico and its people. Therefore, his first trip as a 2020 candidate will be to speak at the Latino Victory Fund summit there.

He will demand an investigation into the response of the Trump administration to Hurricane Maria that devastated the region. It is expected that Democrats will highlight these issues in their campaigns.

Julian Castro will face tough competition

According to USA Today, it will not be a cakewalk for Julian Castro. There will be many other Democrats in the fray and he will have to compete against leaders, some of whom are quite senior.

There could be women like Tulsi Gabbard of Hawaii, Kamla Harris and Elizabeth Warren, apart from former Vice President Joe Biden and New Jersey Sen. Cory Booker.

Incidentally, Hillary Clinton was a contender last time but Donald Trump overcame the competition. However, it's not beyond impossible that woman could claim the White House in 2020 to become the 46th President of the United States.
