So, what is an anti-endorsement, anyway? . . .
Un-herd of in the liberal press? No. . . .
Please notice how the headline tries to blur whether it’s referring to the nation or just the publication “The Nation.”
The Nation Calls for Joe Biden to “Withdraw From The Race” in Stunning “Anti-Endorsement” Column
Mediaite / Nov. 7, 2019 / Charlie Nash“Biden’s long record of poor judgment,” ranging from the Iraq War to Wall Street, “renders him an even weaker opponent for a president whose reelection poses a clear and present danger to America’s survival as a constitutional republic.”
“Stumbling through the primaries, Biden’s zombie campaign crowds out worthier challengers, handing Trump a free pass on the very issues that should be his Achilles’ heel,” the magazine explained, adding, “The Nation therefore calls on Biden to put service to country above personal ambition and withdraw from the race.”
“ . . . It may still be unclear which Democrat is best positioned to beat Donald Trump, but we know one thing: The answer is not Joe Biden.”
