Yes, but that doesn’t mean they are specifically pushing uncle Joseph. Some are quite apprehensive about his proneness to gaffe. Just look at the glee they covered the Harris’s zinger in first debate. I don’t think there’s a concerted effort to push a single candidate, as opposed to 2016 when Fox went all in for Trump, or CNN telecasted his empty podium.
Deep down, no one really truly want Biden, that’s why even his team has been hiding him from campaigning publicly. They are trying to shield him from the extensive coverage in the first few states.
