With current political coalitions, there's no such thing as a great Senate map for Democrats given the (deliberate) bias of the Senate toward rural states. Rather, there are *OK* maps for Democrats (e.g. 2022), terrible ones (e.g. 2018) and various gradients in between.
In 2022, D pickup opportunities would include WI, PA, FL, NC (& possibly AZ and GA depending on the outcome of special elections). Not bad. But those are also all states that voted for Trump! Presidents don't tend to pickup seats in those sorts of states in the midterms.
