With Minnesota Sen. Amy Klobuchar and former South Bend mayor Pete Buttigieg out of the Democratic presidential primary, only Vermont Sen. Bernie Sanders, former Vice President Joe Biden, Massachusetts Sen. Elizabeth Warren, and Hawaii Rep. Tulsi Gabbard remain. Although Gabbard does not appear to have any path to the nomination, she interestingly remains the only candidate left in the race who is a lifelong Democrat and supported Sanders against Hillary Clinton in the 2016 primary, The Guardian reported.
While Sanders has been an Independent for most of his political career and Biden was briefly a registered Independent, Warren was formerly a Republican. Despite Politico noting the bad blood between Gabbard and the Democratic establishment, she is the only remaining candidate in the primary who has been a Democrat for the entirety of her political career.
