While the GOP is more divided than usual this cycle, Democrats are more united. Hillary Clinton has 67 percent in the polls, more than the top five Republicans’ average support combined. Clinton is polling stronger than any contender in the modern era on either side, including incumbent presidents George H.W. Bush in 1992 and Jimmy Carter in 1980. For non-incumbents, Ronald Reagan in 1980 and Al Gore in 2000, each with 45 percent support at this point, come closest to Clinton.

Meanwhile, on the Republican side, the difference between Huckabee and Rep. Paul Ryan of Wisconsin, who ranks fifth according to polls, is only 4 percentage points. That’s by far the most tightly packed the top five candidates have been in our sample. No other year has a first-to-fifth gap less than 10 points.

The difference between first and fifth on the Democratic side is 65 percentage points. That’s the widest gap on record.
