Hillary Clinton stands atop of the Democratic 2016 scrum, set to resume where Bill left off. A second Clinton candidacy would likely put the white vote in play and jeopardize the GOPís dominance in the Old Confederacy. Recent polls put Hillary ahead of possible Republican challengers in vote-rich Texas and in Kentucky, home of Senate Minority Leader Mitch McConnell and Tea Party favorite Rand Paul.
Unlike her husband, Hillary is personally disciplined. Unlike Barack Obama, she has demonstrated an ability to connect with beer-track voters across the country.

To understand why Hillary is particularly dangerous to the Republican Party, recall where the Democratic Party stood on the eve of Billís 1992 run for the White House, poised for what would have been their sixth loss in seven presidential elections.
