Easiest pathway for Democrats to hold the Senate?

[IceSpear]

For the purposes of this poll, let's assume that Republicans pick up MT/WV/SD/AR, Democrats hold NC, and Orman wins and will caucus with the Democrats no matter what. That means in order to retain the majority, Democrats would have to win three of the above six seats. Which three represent the Democrats' easiest pathway?

Wait, haven't you miscounted here, or is it me?  Don't the Dems only need to win two of the above?

If KS goes Dem. and no other GOP seats do, then the GOP needs to flip seven Democratic seats their way to get a majority.  So MT/WV/SD/AR.  GA and KY are already GOP, so the GOP needs three of AK/CO/IA/LA.  So if the Dems win just two of those, then the Senate is 50/50 and Biden breaks the tie, to give them control.
