前佛罗里达州州长杰布·布什正式宣布参选美国总统。他承诺将"用心选举"，"不认为任何事或任何人是理所当然的"。

Polling suggests he has yet to dominate a wide field of Republican candidates.

民意调查表明他还未在共和党候选人之争中获得广泛支持。

Speaking in both English and Spanish, Mr Bush used his speech to appeal to a broadswath of the US electorate - of which minorities have become increasingly more important - not just the Republican's conservative base.

杰布·布什能说英语和西班牙语，他利用这一点向不局限于共和党传统票仓的更广大选民发出了呼吁。这些少数族裔已经变得越来越重要。

"In any language," Mr Bush said, "my message will be an optimistic one because I am certain that we can make the decades just ahead in America the greatest time ever to be alive in this world."

布什说："在任何语言里我的信息都是乐观的。因为我确信我们能让美国的未来几十年成为世界上最伟大的时代。"

Mr Bush also offered some insight into his foreign policy stances.

布什还介绍了他的部分外交立场。

"We keep dependable friends in this world by being dependable ourselves. I will rebuild our vital friendships and that starts by standing with the brave democratic state of Israel," he told the crowd, which erupted in cheers.

他对现场听众说："因为我们自身值得信赖，所以在这个世界上我们拥有值得信赖的朋友。我将重建我们重要的友谊，从和勇敢的民主国家--以色列站在一起开始。"人群中因此爆发出欢呼声。

He also denounced Mr Obama's recent overtures toward Cuba.

他还谴责了奥巴马总统近来对古巴的友好姿态。

"Ninety miles to our south there's a talk of a state visit by our outgoing president," Mr Bush said. "We don't need a glorified tourist to go to Havana in support of a failed Cuba. We need an American president to go to Havana in solidarity with a free Cuban people, and I'm ready to be that president."

他说："向南90英里，有一场谈判，关于我们即将卸任的总统的国事访问。我们需要的不是一个被美化的游客，去哈瓦那支持失败的古巴。我们要的是一名美国总统，前往哈瓦那和自由的古巴人民站在一边。我已准备好成为这样的总统。"
