One barrier to interpreting early results in many states is not knowing just how many counted ballots are from early voting, but one thing we should be able to tell is whether any Senate candidates are performing substantially better than their party’s presidential candidate among the same voters. There has been almost no gap in the polls for Senate and President in many states, as those candidates have had trouble separating themselves from their party’s national reputation. Republicans would likely need a candidate-specific Senate vote in Maine and Michigan; Democrats would likely need one in Montana or Kansas. In tight races like North Carolina, even a small advantage for one party’s Senate candidate over their Presidential nominee could be enough for victory.
