Brazil (25 October): After the 4 October first round, the presidential race goes to a runoff on Sunday 25 October between Flávio Bolsonaro and President Lula, because neither passed 50% of valid votes. Bolsonaro led the first round with about 47.03% to Lula’s 45.16%, a gap of roughly 2.2 million votes. The runoff polls are extremely close. Datafolha has Lula at 47% and Bolsonaro at 46%, while AtlasIntel has it at 50.1% to 49.9%. Both results are within the margin of error.
Serbia (25 October): Serbia is listed for a snap parliamentary election on 25 October. Older calendars gave a different date, so voters and observers should check the latest official announcement. I found little detailed coverage of the campaign, so the main fact to rely on is that this is an early election rather than a scheduled one.
United States (3 November): The midterm elections on Tuesday 3 November will decide control of Congress. Republicans currently hold both chambers. Democrats need a net gain of four Senate seats and three House seats to take a majority. 33 Senate seats are up (13 held by Democrats, 20 by Republicans), plus two special elections. Georgia’s Senate race between Jon Ossoff and a Republican challenger is closely watched, and runoffs on 1 December will settle any Georgia races where nobody wins more than 50%. Early voting is already open in some states, such as North Carolina (15 to 31 October).
New Zealand (7 November): New Zealand votes on Saturday 7 November, after Prime Minister Christopher Luxon announced the date on 21 January. The contest has tightened over the year. The latest 1News-Verian poll (1-5 October) had the two leading parties at 29% and 28%, a one-point gap. Smaller parties polling around 16%, 10% and 9% could decide who forms the next government.
Cabo Verde (15 November): Cabo Verde is listed for a presidential election on 15 November. Election trackers confirm the date, but I found no detailed coverage of candidates or polling. The date should be checked against the national electoral commission before anyone relies on it.
Taiwan (28 November): Taiwan holds local elections on 28 November, choosing 22 magistrates and mayors among other posts. They are not national elections, but they are seen as a gauge of party strength before the next national cycle. The ruling DPP of President Lai Ching-te, the KMT under Cheng Li-wun, and the TPP under Huang Kuo-chang will all read the results closely. The KMT and TPP have discussed working together.
The Gambia (5 December): The Gambia is listed for a presidential election on 5 December, though one tracker says only that it is “expected by December” and gives 1 December. The two dates are close but not the same, so the final date still needs official confirmation. A parliamentary election is listed for 10 April 2027.
