Voter enthusiasm has been in short supply for both Hillary Clinton and Donald Trump through the fall campaign and continues to lag excitement about candidates on the ballot four years ago. At this point in 2012, 64 per cent of Obama supporters said they were "very enthusiastic" about him; Romney was only narrowly behind at 61 per cent.
Trump and Clinton continue to run nearly even in overall vote preferences, with Trump at 46 per cent and Clinton 45 per cent in a four-way contest in the poll conducted Thursday through Sunday. The margin is a mirror 48-47 Clinton-Trump split when third-party candidates are asked which major-party candidate they lean toward, a comparison which has grown in importance as support declines steadily for Libertarian Gary Johnson and the Green Party's Jill Stein.
Over 1 in 5 likely voters identified in the Post-ABC poll report as having already voted (21 per cent), while about one-quarter say they plan to vote early or by mail (24 per cent,) and a slight majority plan to vote in-person on Election Day. The level of early voting so far is roughly in line with expectations given the 24.7 million early votes tracked so far by the United States Election Project, which amounts to 19 per cent of the 129 million ballots cast in 2012.
Clinton has a modest 54-41 per cent edge among early voters in an average of the three most recent tracking poll waves, while Trump leads by a 50-39 per cent margin among those looking to vote on Election Day; those who anticipate voting early are more evenly split. Those breakdowns should be treated with caution, given both the sizable 8.5-point margin of sampling error around that result as well as general challenges in tracking attitudes among a rapidly growing population.
Older Americans have flocked to vote early, with 38 per cent of senior likely voters saying they have done so, compared with 18 per cent of those ages 40-64 and 17 per cent of voters younger than that. Women are slightly more apt to report voting early than men (26 vs. 19 per cent), as are voters in urban areas (28 per cent) compared with suburban and rural voters (19 per cent and 22 per cent).
The daily tracking poll's latest four-night wave finds voters splitting sharply along traditional political divisions, with Trump's previously lagging support among core Republican groups now nearly matching Clinton's wide support on the left. Trump holds 78 per cent support among white evangelical Protestants, 77 per cent among conservatives, 68 per cent among rural voters and 59 per cent among white men. Clinton answers with 81 per cent support among liberals, 67 per cent of those identifying with no religion, 60 per cent of those in urban areas and 72 per cent among non-whites.
Clinton and Trump receive similar support among fellow partisans, but Trump maintains an 18-point edge among political independents, significantly higher than Republicans have held in recent elections. Looking deeper at that group over a seven-day stretch, 77 per cent of independents who say they lean Democratic prefer Clinton while a similar 80 per cent who lean Republican favour Trump. But Trump holds a sizable 53-28 per cent advantage among voters who say they don't lean toward either party, a group that accounts for about 10 per cent of likely voters.
