President Trump's former campaign chairman Steve Bannon reportedly said the president’s most dangerous 2020 opponents would be former Rep. Beto O’Rourke and Sen. Kamala Harris, D-Calif.

“Beto on the ticket with Harris is the most dangerous ticket for Trump,” Bannon told a conservative group in Italy, according to the Daily Beast.

“But don’t forget, the vampire is still alive: Hillary Clinton,” Bannon added.

O’Rourke, 46, announced a run for president this month. The former representative from Texas is a rising star in the Democratic Party who came to prominence during his unsuccessful 2018 bid to unseat Texas Republican Sen. Ted Cruz. O’Rourke lost by less than 3 percentage points, despite Trump winning the state by more than 7 points in 2016.

The 54-year-old Harris, who announced she was running in January, is a well-known senator and former prosecutor from California. A recent poll shows that O’Rourke and Harris are in a dead heat, tied at 8 percent each among Democratic primary voters. They both trail far behind former Vice President Joe Biden and Sen. Bernie Sanders, I-Vt.

Biden has yet to announce his candidacy but is expected to soon. Sanders joined the race in February.
