(Reuters) - Democrats say their advantage in early voting has allowed Joe Biden's presidential campaign to sharpen its get-out-the-vote operation by targeting a smaller universe of potential supporters, while Republicans brace for an all-or-nothing scramble to turn out votes for President Donald Trump on Nov. 3.

Early voting, both by mail and in-person, has surged to record highs, with Americans energized by a high-stakes election while also worried about crowded polling places amid the coronavirus pandemic. State data on who has voted early show ballots cast by registered Democrats so far outpacing those cast by registered Republicans.
