As South Dakota campaigns launch, Thune mulls retirement
He has delayed a reelection announcement as he considers retirement.
Thune has held his Senate seat for three terms and wields power as the second-ranking Republican in Senate leadership.
He had planned to announce a reelection decision over the holidays. But the senator has made no indication he is any closer to a decision on seeking a fourth term.
If he retires, it could upend national Republican politics and create a scramble within the South Dakota GOP to fill the void.
With the Senate in session this week — and a campaign announcement not expected until he can travel back to his home state — the waiting will likely last at least several more days.
