If I recall,there is the equivalent of a Chavez Caucus in Congress. Where are they now when Chavez is in the process of imposing a dictatorship in Venezuela?

He has already expropriated private property (including assets of American-owned firms) and restricted free speech in his nation (the networks he has shut down, the papers that are now closed).

Now he is on the verge of "winning" a referendum that will lead to a permanent dictatorship-lifetime tenure, no term limits- that gives him unlimited power to suspend due process, censor news organizations, control all government funds with no oversight or transparency, handpick leaders for new administrative regions he wants to create, and give him  a raft of powers that should shock the conscience of any Democratic who believes in his party's principles.

The proposed changes would eliminate the central bank's independence, sharply limit the role and definition of private property and emasculate the powers of governors and mayors, allowing Mr. Chávez to literally redraw the political map of Venezuela. Under the new charter, Mr. Chávez could unilaterally set and dispose of the nation's foreign-currency reserves. He would be able to appoint or dismiss vice presidents who would rule over the country's 24 states, which he intends to group into six to eight regions.

Perhaps, most important for Mr. Chávez, the changes would allow for his unlimited re-election 

Already Mr. Chávez controls the congress, the courts, the electoral commission and most state and city governments. He has nationalized the telephone company and main power company and increased government control over the oil industry.
