Chavistas in Venezuela consider that there are 2 or 3 credible pollsters in the country: IVAD, PLM and Datanalisis. Many times, their calculation mistakes were in favor of Chavez, as in the 2007 referendum:
"Las tres encuestadoras más reconocidas de Venezuela dieron una amplia mayoría al Sí frente al No en sus primeros resultados de la contienda para refrendar las reformas constitucionales propuestas por el primer mandatario Hugo Chávez Frías...PLM Consultores, Datanálisis y el Instituto Venezolano de Análisis de Datos (IVAD), reflejan en sus primeros conteos grandes similitudes en los resultados, arrojando que el pueblo venezolano ha elegido por los cambios a la Constitución que encaminarán a Venezuela en un rumbo de profundización hacia el socialismo."

Datanálisis: 57,3% aprueban la labor del presidente Chávez, 5% más que en el mes de junio
http://www.aporrea.org/actualidad/n141476.htmlAll their polls get published in chavista media such as APORREA.ORG, which is basically the voice of the revolution in the internet.
By the way, the last polls from IVAD, the favorite of the government, reflect as well this slip in popularity that Chavez is showing.
But don't worry, if you had taken time to read the article, you would have understood that "Yet Chavez still faces no strong political opponents with anywhere near as much support" and that "Until now, there's been no one else who can compete with him". His popularity is eroding a little like in the past, don't panic.
