NEW YORK — Whether or not Republicans ultimately confirm President Donald Trump’s Supreme Court nominee, some on the front lines of the GOP’s midterm battlefield fear the party may have already lost.

In the days after a divided nation watched Brett Kavanaugh and his accuser Christine Blasey Ford deliver conflicting stories about what happened when they were teenagers, Republican campaign operatives acknowledged this is not the fight they wanted six weeks before Election Day.

Should they give Kavanaugh a lifetime appointment to the nation’s highest court after Ford’s powerful testimony about sexual assault, Republicans risk enraging the women they need to preserve their House majority. Vote him down, they risk enraging the party’s defiant political base.

In swing state New Hampshire, former Republican Party chair Jennifer Horn said Republicans are “grossly underestimating the damage that would be done” at the ballot box in the short and long term should they confirm Kavanaugh.

We pride ourselves, as Americans, on the idea that we root for the underdog. We don’t want the Patriots to win; we want the Eagles. We don’t want Cobra Kai to win; we want Daniel to do that swan-kick thing. And we say we don’t want the Yankees to win their 200th World Series — but, tragically, we do. Deep in our American hearts, it seems, we want the rich unsympathetic bullies to continue their baseball dominance. Deep inside our American spirit, there’s a murky shadow.

Anyway, we took that Facebook data and did politics to it.

Here was our thinking: What if we took the county-level baseball fan data and compared that to county-level 2016 election results? In theory it would allow us to see the places that were both most supportive of particular teams and most supportive of individual candidates. It isn’t perfect: We basically applied the percentage of fans of each team in a county to the number of votes cast for Donald Trump, Hillary Clinton and third-party candidates in each place. But overall, the results are clearly representative.

We begin at the 10,000-foot level. Here is each team, represented by a pie chart showing the total number of voters favoring each team (the size of the pie) and the split of votes among those fans (the pie slices).

SAN FRANCISCO — The post went up quietly on Facebook’s internal message board last week. Titled “We Have a Problem With Political Diversity,” it quickly took off inside the social network.

“We are a political monoculture that’s intolerant of different views,” Brian Amerige, a senior Facebook engineer, wrote in the post, which was obtained by The New York Times. “We claim to welcome all perspectives, but are quick to attack — often in mobs — anyone who presents a view that appears to be in opposition to left-leaning ideology.”

Since the post went up, more than 100 Facebook employees have joined Mr. Amerige to form an online group called FB’ers for Political Diversity, according to two people who viewed the group’s page and who were not authorized to speak publicly. The aim of the initiative, according to Mr. Amerige’s memo, is to create a space for ideological diversity within the company.

The new group has upset other Facebook employees, who said its online posts were offensive to minorities. One engineer, who declined to be identified for fear of retaliation, said several people had lodged complaints with their managers about FB’ers for Political Diversity and were told that it had not broken any company rules.
