2 percent

Donald Trump does not have a lot of support among African-American voters. Just 2 percent of black voters said they were backing Trump in a new national poll by McClatchy-Marist, and he picked up only 1 percent in two other recent national surveys. [@Taniel]

4th place

Trump is also not doing very well among voters aged 18 to 29. When asked who they would vote for in an election held today, 41 percent backed Hillary Clinton, according to that Marist survey. Another 23 percent said they would support Libertarian Gary Johnson, and 16 percent said they would support Green Party candidate Jill Stein. Oh, and 9 percent said they were for Trump, which lucky for him means he is at least beating some candidate named “undecided,” currently with 8 percent of the youth vote. [McClatchy]

30-40 capybara

Approximate number of capybara — which everyone should know is a large rodent (well, everyone who watched a lot of “The Wild Thornberrys” as a kid like I did) — who reside inside the Rio Olympic golf course perimeter. As far as wildlife you’re liable to encounter in Brazil, you could do worse than a capybara. [SF Gate]
