Venezuelan President Hugo Chavez's Socialist Party won a majority of votes and seats in parliamentary elections held Sept. 26. But the margin of that victory was considerably smaller than those of the past, and his opponents are claiming that they are the big winners in the ballot.

Mr. Chavez lost the unassailable majority he held in the legislature and, in theory, will be forced to negotiate with the opposition. In fact, Mr. Chavez has shown little patience for such niceties and has, when challenged, demonstrated a preference for running around constitutional hurdles, rather than working through them.

Mr. Chavez has been pressing his "Bolivarian Revolution" since he took power over a decade ago. The former army lieutenant colonel has championed a nationalist- populist-socialist domestic agenda and ridden opposition to U.S. policies to regional and international prominence.
