Kentucky's Sen. Rand Paul, whose libertarian streak and wariness of war have set him apart from many fellow Republicans, that is expected to announce his candidacy for president in 2016 on Tuesday — but according to an NBC analysis, he's unlikely to win his party's nomination. With his unorthodox views and approach, he faces long odds, largely because he's taken foreign policy stances that are anathema to the GOP's power players. He was elected to the Senate in 2010 as part of the tea party-backed wave of Republicans more focused on fiscal issues and on repealing Obamacare, but now, he and his would-be rivals face a growing list of foreign policy challenges. Most of his GOP colleagues say President Barack Obama has weakened U.S. influence abroad, but Paul has broken ranks often, backing Obama's reset with Cuba, pledging to end the NSA's data collection and suggesting direct talks with Iran.
