On Monday, The Daily Beast reported that the authors of a popular book for believers in the QAnon conspiracy theory are in a bitter fight over whether or not to release an audiobook version.

QAnon: An Invitation to The Great Awakening came out last year and peaked near the top of the Amazon bestseller list in March. One of the book's co-authors, Dustin Nemos, is publicly attacking another co-author, who goes by the name of "JoeM," for his "petty and hostile and paranoid" refusal to help produce an audiobook, and notes that it is necessary because a disproportionate number of QAnon believers are elderly, have bad eyesight, and may not be able to read the book as text. JoeM, for his part, has accused Nemos of being a "grifter" who is trying to make a buck off of true believers.

The world population is expected to climb to 9.7 billion in 2050 from 7.7 billion today, with the population of sub-Saharan Africa doubling, a United Nations report released Monday said.

The population could then grow to 11 billion by 2100, according to the United Nations Department of Economic and Social Affairs's "World Population Prospects" report.

The study paints a picture of a future in which a handful of countries see their populaces surge as life expectancy lengthens while the global growth rate slows amid declining fertility rates.

By 2050, more than half of the world's population growth will be concentrated in just nine countries: India, Nigeria, Pakistan, the Democratic Republic of Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States.

President Donald Trump has little to promote for 2020, so political analysts on MSNBC think that he'll likely spend the campaign working to tear everyone else down.

Howard Fineman noted that if Trump intends to do a "tear down" campaign, the most important things Democrats will have are policy proposals to set themselves apart from a White House that is unwilling to pass anything through Congress.

"It's just a question of can he do what he did in 2016 and 2018, which was, frankly, mobilize voters in a fear-tactic kind of way," said Fineman during Monday's "Meet the Press."

Host Kasie Hunt said that it seems the new Trump poll numbers show that his base is losing enthusiasm as they go into the election.
