This is a strong signal. Marist is traditionally one of the most Dem-leaning non-partisan polls out there.
This isn't true? They nailed 2022 basically right on the dot. They have been more dem-leaning in the past, but you could say the same about NYT/Siena for example too (and just about everyone else in 2020)
Marist's definitely voting was the most accurate to the results in 2022, so them having Trump +7 sounds about right; lines up with the average right now which seems to be about Trump +7 in TX.
