Axios says Brown is still in big danger. Is he?

“Smart Brevity” DC Beltway publication Axios is reporting that Sherrod Brown remains in big danger in his Senate re-election campaign.

Yes, but: There are some Senate Democrats who are keeping Harris at arms length.

• Sen. Sherrod Brown (D-Ohio) has endorsed Harris, but the presidential campaign did not make a stop in increasingly-red Ohio. And Brown is in a similar bucket as Tester, faced with having to outperform Harris and Walz to keep his seat.

This seems a little at odds with what Axios is reporting, however:

Is Brown safe so long as Harris stays away from Ohio? Or is something else going on here?
