I think because Moreno managed to step in his own big pile of shit, the one worrisome seat might be Tester's.
I am going to offer some advice based on what happened back in 2022 with the "media narrative" that got generated from wholesale acceptance of the tainted poll aggregators due to a bunch of bad/partisan polls that got rolled into the aggregates. This should be a "lesson" to look at because I expect the same is happening again and "we" (editorial) fall for it -

The Red Wave Washout: How Skewed Polls Fed a False Election Narrative
By Jim Rutenberg, Ken Bensinger and Steve Eder
Dec. 31, 2022
Senator Patty Murray, a Democrat, had consistently won re-election by healthy margins in her three decades representing Washington State. This year seemed no different: By midsummer, polls showed her cruising to victory over a Republican newcomer, Tiffany Smiley, by as much as 20 percentage points.
So when a survey in late September by the Republican-leaning Trafalgar Group showed Ms. Murray clinging to a lead of just two points, it seemed like an aberration. But in October, two more Republican-leaning polls put Ms. Murray barely ahead, and a third said the race was a dead heat.

Ms. Murrays own polling showed her with a comfortable lead, and a nonprofit regional news site, using an established local pollster, had her up by 13. Unwilling to take chances, however, she went on the defensive, scuttling her practice of lavishing some of her war chest she amassed $20 million on more vulnerable Democratic candidates elsewhere. Instead, she reaped financial help from the partys national Senate committee and supportive super PACs resources that would, as a result, be unavailable to other Democrats.
A similar sequence of events played out in battlegrounds nationwide. Surveys showing strength for Republicans, often from the same partisan pollsters, set Democratic klaxons blaring in Pennsylvania, New Hampshire and Colorado. Coupled with the political factors already favoring Republicans including inflation and President Bidens unpopularity the skewed polls helped feed what quickly became an inescapable political narrative: A Republican wave election was about to hit the country with hurricane force. Democrats in each of those states went on to win their Senate races. Ms. Murray clobbered Ms. Smiley by nearly 15 points.

The tactic would be to poison the aggregators with partisan polls, forcing Democrats to
misappropriate money to what really are SAFE seats instead of providing to others who could have used the money to tip the balance their way.
The case above of Patty Murray in 2022, who was declared as being "tied" in her race, ultimately resulted in her WINNING by 15%. The same bullshit was going on here in PA with John Fetterman, where the "narrative" and "the polls" claimed that Oz would win. Fetterman went on to win by something like 4%, which was outside of the MOE.
