I'm going to paste in part of my comment on another thread:

Something important to know about the two people who were shot: until her death, Melissa Hortman was a member of the Minnesota State House of Representatives; and John Hoffman is a member of the Minnesota State Senate. Both were Democrats.

And up until they were shot, the Minnesota House had 134 Members: 66 Republicans vs 67 Democrats (with one seat empty to be filled later). And the Minnesota Senate had 67 members: 33 Republicans and 34 Democrats. If the assassinations had both been successful, both chambers would have been tied. As it is, they're only saying that Hoffman is "stable", but there are no further details.
