Seib points out why the current political landscape with the popularity of Trump and Sanders reflects demographic, economc and social changes in America compared to when Geroge H.W. Bush won the election in 1988 and Bill Clinton won in 1992. The Republican party is more populist, with older Americans, more Southern and conservative, making it harder for Jeb Bush or Wall Street backed candidates. The Democratic Party more liberal, more popular on both the east and west coast of the U.S., with younger Americans, diverse demographic groups, making it harder for Hillary Clinton as an establishment candidate. A Journal/NBC poll of Oct. 2015 shows 28% of Republicans describing their views as very conservative, and 26% of Democrats saying they are very liberal. Yet there is another aspect that will show up once the primaries are over. And this is the steady group of somewhat conservative and moderate combined in the Republican Party of 64%, and the steady group of somewhat liberal and moderate in the Democratic Party of 62% in the 2015 Journal/NBC poll. The moderates are up from 26% in the above 1990 poll to 31% in the 2015 poll for the Republican Party, and from 26% to 33% in the Democratic Party. So that one sees about a quarter of people polled in each party pushing for fringe views and a countervailing trend for moderate or close to moderate views with about two thirds support in the 2015 Journal/NBC poll for each party....
