Boebert, billionaires' tax and other midterms races still to watch

Democrats have been celebrating their sweeping midterm victories, including flipping control of both chambers of Congress - but several critical races were still too close to be called on Thursday.
Votes are still being counted in two surprisingly tight Senate races in historically red states, Alaska and Mississippi, which could decide the true scale of Democrats' majority.
Several US House races are also too close to call, including that of Lauren Boebert, a prominent ally of President Donald Trump, who is facing a tight re-election contest in Colorado against Democratic challenger Eileen Laubacher.
