Opinion of Mr X.

[TML]

Didn't he unironically think the jogger thing was actually a big deal that would doom Fetterman?

I think this is part of his bias toward establishment/corporate/centrist candidates (e.g. he feels that the DSCC was right to coronate candidates in Democratic Senate primaries from the mid-2000s to 2020, even though many such candidates ended up falling short in their respective general election contests).
