In Chapter 11 of A People's History of the United States how close did the two races in the South come during the populist struggles?

In Chapter 11 (page 286 of my edition of the book), Zinn
quotes the famous historian C. Vann Woodward as saying that the two races were never
closer than they were "during the Populist struggles."  Zinn does not dispute this
statement.

However, Zinn does point out that there was a
great deal of racial tension even among the Populists.  The Populists were ambivalent on
the issue of race.  For example, he points out that a Populist-controlled legislature in
Georgia passed more anti-black bills than any other legislature had in a single year. 
Yet, in 1896, the Populists in Georgia had a platform that denounced lynching.  Some
Populist groups had large black memberships while others did
not.

The record, then, is mixed.  Even so, Zinn seems to
agree with Woodward that the two races came closer together during the Populist era than
they ever had before.
