According to a 2018 study by the Pew Research Center, 53% of Wall Street Journal readers identify as Republican, while 33% identify as Democrat. This makes the Wall Street Journal one of the most Republican-leaning major newspapers in the United States.
It's important to note that the Wall Street Journal is a business newspaper, and as such, its primary focus is on financial and economic news and analysis. While it does cover political news, it does not typically take a strong ideological stance.
