Senator Elizabeth Warren announced her intentions to run in 2020 on New Year's Eve. Warren is the first major Democrat to announce a bid for the White House. In a four-minute video posted on YouTube, Warren said, "the middle class is under attack." Warren traveled to Iowa this past weekend, which is the first state to kick off election season with its famous Iowa Caucus. Once a Harvard professor, turned U.S. Senator, Warren is sure to put up a fight for the Democratic nomination.

Some other names that have been thrown around include Beto O'Rourke, the Senate hopeful and former Congressman from Texas. He gave Ted Cruz a run for his money during the midterms, and many believe that he is the candidate that could win Texas and Arizona in a general election.

Julian Castro, another Texan, has also mulled intentions to run. He posted a video in which he said he would not give a final decision until January 12th. Castro is a former cabinet secretary for former President Obama and the former Mayor of San Antonio.

Senator Bernie Sanders is once again being mentioned. He ran against Hillary Clinton in the primaries and proved that he had a strong base of supporters. Many believed that he wouldn't even come close to winning the nomination back then, but he proved everyone wrong.

Another big name being brought up: Former Vice President Joe Biden. Biden leads almost every single poll among Democrats and he is seen as someone who really has the potential to beat Trump in general election.

A newcomer to the pack is Kamala Harris. Harris is a Senator from California and several think that if she doesn't win the nomination or doesn't run for the nomination, that she will end up on the ticket as a Vice Presidential nominee. After her fiery exchanges with then-Supreme Court Nominee Brett Kavanaugh, she propelled herself into the national spotlight and is considered to be the candidate that can pull progressives and centrists together.

Kirsten Gillibrand, another Senator, might also run. The Senator from New York has thrust herself into the forefront of women's issues after she told then-Senator Al Franken, a fellow Democrat, to step down after allegations of sexual misconduct. She is also a major critic of the White House and has also called for the President himself to resign.
