showdown and dog run

google finance news 列出了數則關於 Obama 推動的美國健保法的新聞
發現兩個關鍵詞 : showdown 與 dog run(dog-run)

"Supreme Court: Pre-election health care showdown"
"Obama health law case could dog run"

showdown 攤牌/亮出底牌決勝負
(從撲克牌遊戲來的辭彙, 指最後時刻 將覆蓋的底牌(down cards)掀開(show off) 決勝敗)

dog run : "a fenced off area where dog can get exercise and be kept confined"
指圍籬圈起來 讓狗狗運動的區域 ...
那 "Obama health law case could dog run" 到底何意?
