I don't understand how someone can say this with a straight face. Whitewater was a New York Times created scandal. It was the New York Times that ran cover for the Bush administration in invading Iraq. It was the New York Times that a week before the 2016 election ran dueling stories that played up the Clinton e-mail story and simultaneously absolved Trump of any links to Russia. All of these stories got widespread media attention by the so-called left-leaning media. The Whitewater story never amounted to anything, the grounds for invading Iraq were all lies, and the Clinton e-mail story lead to nothing while Trump's ties led to a long-running investigation that led to jail time for several members of Trump's campaign.
If Biden wins, then by spring, the leading story in the "left-leaning" media will be that we need to cut social spending to combat the deficit. The deficit miraculously stops being a story whenever a Republican is in the White House, and becomes a major priority whenever a Democrat is in the White House. Just because people in the media think that racism is bad doesn't make the media left-leaning.
