For things other than the EURef and the US elections.
Today, the big one is Austria, which looks to be absurdly close. Neither of their big two parties got into the final round, so it's between Van Der Bellen and Hofer; VDB is an old Green, Hofer is fairly populist-right wing in the mould of Trump or UKIP (though his party has more extreme fascist roots).
On the day, Hofer held a small lead, but postal ballots (representing Austrians outside the country, and probably some wealthier and more elderly Austrians) seem to be heavily favouring VDB, unsurprisingly. Current estimates are running at 49.57% for Hofer and 50.43% for VDB, but there's still half the postal votes to be counted...
