By late Tuesday night or Wednesday morning, officials from both parties say we should know whether or not the Democrats have won the House. Until then, everyone is on edge — and the tension is only going to get worse through the long election night.
What they're saying: Democrats remain "cautiously optimistic," one strategist told me, especially "after living through 2014 and 2016" when Democrats had high hopes but suffered major losses. President Trump is sounding the alarm by disputing CNN polls and warning of potential illegal voting. And a national Republican operative texted me: "It's going to be a bad night in the House."
