Days of heavy rains, floods and landslides in southeast Brazil have killed at least 54 people and displaced 30,000 others, AP reports.

The big picture: Brazilian President Jair Bolsonaro said the military had been mobilized
to help as over 100 cities had declared a state of emergency, per CNN. While rains were dissipating Monday, they're expected to return later this week in some places, AP notes.

Republicans, win or lose next week, face a big — and growing — math problem.

The state of play: They're relying almost exclusively on a shrinking demographic (white men), living in shrinking areas (small, rural towns), creating a reliance on people with shrinking incomes (white workers without college degrees) to survive.

With less than a week until the 2020 election, researchers have expressed concern that the information ecosystem today is ripe for an unprecedented level of exploitation by bad actors, particularly hyper-partisan media and personalities on the right.

Why it matters: The misinformation-powered right-wing media machine that fueled Donald Trump's 2016 victory grew stronger after that win, and it's set to increase its reach as a result of the upcoming election, whether Trump wins or loses.
