With the likelihood of Pence becoming the VP, this opens up the governors race in the dems eyes. Adding a Byah into the race may help win the senate, in the dems eyes.
The dems are gambling here. They will either win big or loose big.
With Birch III running, will this also put Indiana more in play for the Witch. My aging mind seems to remember the Bayh name being golden in Hoosier state politics.
Given that Gregg (D) in Indiana isn't running strongly, it may also give the Indiana GOP an excuse to replace Pence, who was struggling more than he should be in retaining his governor's seat. Pence has not handled a few legislative things well in the past year or so, and the Dems thought they could run anyone with a heartbeat and win the governor's seat.
