The Clinton and Bush dynasties face challenges from inside their own parties

The open sniping between President Trump and the Bush family comes at the same time that veteran Democratic insider Donna Brazille is revealing her doubts about Hillary Clinton’s candidacy and the process by which she beat Bernie Sanders.

It’s not a mere coincidence. The dynasties at the top of the two major parties for the past quarter-century are under attack from within as never before. Trump ran as a rejection especially of George W. Bush in the 2016 Republican primaries and used Jeb Bush as a foil during the debates, riding that anti-establishment wave all the way to the White House.
