The fundraising success of Democratic Sen. Elizabeth Warren of Massachusetts is increasing speculation she will run for the Democratic presidential nomination in 2020.
Warren, who is due to run for a second term as senator in 2018, has raised $12.8 million in campaign contributions to date, according to Politico.
This is more than nearly any incumbent senator at this stage in the electoral cycle.
It is not clear how Warren will proceed. Politico noted she is balancing between those advisers who suggest it is best for her to focus on securing a large majority in her Senate re-election race, and others who want her to explicitly declare her intention to run in 2020.
Warren met during 2017 with individuals she has disagreed with in the past, including former President Barack Obama. In addition, she has employed researchers to examine her past career for political vulnerabilities. Both of these steps have been interpreted as preparation for a presidential bid.
The Massachusetts senator's two main potential competitors are seen as Independent Sen. Bernie Sanders of Vermont and former Vice President Joe Biden.
Warren has emerged as one of the main opponents of the Trump administration, especially following an incident in the Senate when Senate Majority Leader Sen. Mitch McConnell of Kentucky prevented her from giving a speech opposing the appointment of former Sen. Jeff Sessions of Alabama as attorney general.
"Sen. Warren was giving a lengthy speech," McConnell said at the time, according to The Hill. "She had appeared to violate the rule. She was warned. She was given an explanation. Nevertheless, she persisted."
#ShePersisted was subsequently used by Warren as a hashtag and helped make her a leader of the "resistance" to Trump in the eyes of liberal and progressive activists.
She has also sharply criticized Republicans in the Senate. During a debate over the GOP's tax reform in December 2017, she stated that Republicans have only one principle left, "Reward billionaire campaign donors," Politico reported.
It isn't just some of Warren's supporters who are urging her to run. Some Republicans hope she will be the presidential nominee, too.
"I'd be glad to donate," Ron Kaufman, a Republican National Committeeman from Massachusetts, said in jest to The Kansas City Star. "I think she's probably unelectable as president."
Some Republicans believe Warren would unite the GOP behind Trump, whereas a more "moderate" Democratic candidate would stand a better chance of picking up votes from GOP supporters disillusioned with the current president.
A Trump fundraiser described the prospect of Warren's candidacy as "a dream come true."
