It's a bad headline: seems easy to believe that there's just a lot more journalists around today than there were in the world wars.
Much better would be to highlight from the body of the article that the death toll is also more than have been killed in the invasion of Ukraine. That one's modern, well-covered by media, Russia has repeatedly targeted civilians, and Russia's been attacking for longer. So to have still killed more journalists makes it clear that it's deliberate.
Responsibility lies with "The Democrats" (some sort of far away secret group that I can't influence) and not with any American. If those Democrats can't give me my perfect candidate, then I'll just give up and let the fascists win. Also, I can't figure out why they won't do this--my ideal liberal candidate would appeal to the majority of Americans!
