“Sen. Barack Obama won the Wisconsin Democratic primary and the Hawaii caucuses decisively last night, extending his winning streak to ten consecutive contests and dealing another significant blow to Sen. Hillary Rodham Clinton, whose imperiled presidential candidacy now hangs on the outcome of showdowns in Ohio and Texas in two weeks. After a week of sparring that included the first negative ads of the campaign, Obama emerged victorious in the critical general-election battleground state of Wisconsin, and was treated to favorite son status with a lopsided win in Hawaii, where he was born. … In Wisconsin’s Republican primary, Sen. John McCain (Ariz.) won an easy victory over former Arkansas governor Mike Huckabee, moving him ever closer to clinching the party’s nomination.” (02/20/08)
