Barely 18 months before Iowa's influential first-in-the-nation 2016 presidential contest, potential presidential candidate and former Secretary of State Hillary Clinton today holds a more commanding position for the nomination than any non-incumbent White House candidate has ever enjoyed, according to every national poll. National surveys continue to name her the first choice of basically seven out of 10 Democratic primary voters to be the party's 2016 nominee. But more importantly, according to the respected Wall Street Journal-NBC News poll, 55 percent of Americans now rate Clinton "knowledgeable and experienced enough to handle the presidency." This is a rare political strength. From Republican pollster Bill McInturff, who, with Democratic pollster Peter Hart, conducts this Wall Street Journal-NBC survey, comes this: "Never underestimate how incredibly powerful it is to (be able to ) say you're knowledgeable and experienced enough to handle the presidency. To start a race with that is an extraordinary compliment."
