Sen. Joe Biden, D-Del., on Sunday guaranteed that if elected, Sen. Barack Obama., D-Ill., will be tested by an international crisis within his first six months in power and he will need supporters to stand by him as he makes tough, and possibly unpopular, decisions. Mark my words," the Democratic vice presidential nominee warned at the second of his two Seattle fundraisers. "Remember I said it standing here if you don't remember anything else I said. Watch, we're gonna have an international crisis, a generated crisis, to test the mettle of this guy. And he's gonna need help. He's gonna need you ... to use your influence, your influence within the community, to stand with him. Because it's not gonna be apparent initially ... that we're right. Gird your loins," Biden told the crowd. "We're gonna win, but this is not gonna be an easy ride. The next president is gonna be left with the most significant task. It's like cleaning the Augean stables, man. He's gonna need your help. Because I promise you, you all are gonna be sitting here a year from now going, 'Oh my God, why are they there in the polls? Why is the polling so down? Why is this thing so tough?' We're gonna have to make some incredibly tough decisions in the first two years. So I'm asking you now ... [to] be prepared to stick with us. There are gonna be a lot of you who want to go, 'Whoa, wait a minute, yo, whoa, whoa, I don't know about that decision'," Biden continued. "Because if you think the decision is sound when they're made, which I believe you will, they're not likely to be as popular as they are sound. Because if they're popular, they're probably not sound."
