Steve Bannon: Kamala Harris and Beto O'Rourke have "best shot" against Trump

Former White House chief strategist Steve Bannon believes Sen. Kamala Harris (D-Calif.) and former Rep. Beto O'Rourke (D-Texas) are the only real Democratic match against President Trump's 2020 re-election bid, per Politico.

Yes, but: Bannon still thinks Trump will win a second term in the 2020 election, as he explained in an interview Friday on CNBC's "Squawk Box." He added that Hillary Clinton will be "waiting for the call" to run in 2020, even though Clinton has made it clear she does not plan to run next year.
