I have yet to see good news about Thune...please post your sources.
Just go to the South Dakota election results page and watch the changes as the west-river precincts come in. Johnson was up 4500 votes a bit ago. Now it's only 2500. Pennington County alone should give Thune the votes he needs to catch up, and the rest of west-river SD should give Thune a slim victory.
