Republican Split--What's New?

NYTimes has a piece today on a split in the Republican party, between the Trump-Cruz faction and the "establishment".  I think it's overdone.  I remember the Republicans were split:

• between the Taftites and Eisenhower Republicans in the 1950's.
• between Rockefeller and Nixon in 1960 (the Treaty of Fifth Avenue)
• Goldwater and establishment in 1964
• Ford and Reagan in 1976
• Reagan and John Anderson in 1980
• Bush and Buchanan in 1992
• etc. etc.

While usually the ticket could and would bridge the difference (i.e., Nixon and Agnew; Reagan and Bush), there might be problems this year.  Trump and Rubio are doable, perhaps Cruz and Christie, or Cruz and Kasich.  Christie and Cruz might be also.
