No, Mr. John Podesta, actually it is the Democrat party that is more like a "cult worthy of Jonestown". To Wit:
The move of Peoples Temple headquarters to San Francisco in 1975 invigorated Jones' political career. After the Temple served an important role in the mayoral election victory of George Moscone [Democrat] in 1975, Moscone appointed Jones as the Chairman of the San Francisco Housing Authority Commission.
Unlike most other figures deemed as cult leaders, Jones was able to gain public support and contact with prominent local and national United States politicians. For example, Jones and Moscone met privately with vice presidential candidate Walter Mondale [Democrat] on his campaign plane days before the 1976 election and Mondale publicly praised the Temple. First Lady Rosalynn Carter [Democrat] also personally met with Jones on multiple occasions, corresponded with him about Cuba, and spoke with him at the grand opening of the San Francisco DEMOCRATIC Party Headquarters where Jones garnered louder applause than Mrs. Carter.
In September 1977, Willie Brown served as master of ceremonies at a large testimonial dinner for Jones attended by Governor Jerry Brown [Democrat] and Lieutenant Governor Mervyn Dymally [Democrat] and other political figures. At that dinner, while introducing Jones, Willie Brown [Democrat] stated "Let me present to you what you should see every day when you look in the mirror in the early morning hours.... Let me present to you a combination of Martin King, Angela Davis, Albert Einstein... Chairman Mao." Harvey Milk [Democrat], who spoke at political rallies at the Temple, wrote to Jones after a visit to the Temple: "Rev Jim, It may take me many a day to come back down from the high that I reach today. I found something dear today. I found a sense of being that makes up for all the hours and energy placed in a fight. I found what you wanted me to find. I shall be back. For I can never leave."
In his San Francisco Temple apartment, Jones hosted San Francisco radical political figures such as Angela Davis for discussions. He spoke with friend and San Francisco Sun-Reporter publisher Dr. Carlton Goodlett about Jones' remorse regarding not being able to travel to socialist countries such as People's Republic of China and the Soviet Union, speculating that he could be Chief Dairyman of the Soviet Union. After his criticisms caused increased tensions with the Nation of Islam, Jones spoke at a huge rally healing the rift between the two groups in the Los Angeles Convention Center attended by many of Jones' closest political acquaintances.
While Jones forged media alliances with key columnists and others at the San Francisco Chronicle and other media outlets, the move to San Francisco also brought increasing media scrutiny. After Chronicle reporter Marshall Kilduff encountered resistance to publishing an exposť, he brought his story to New West Magazine....

Clearly it is the Democrat party that has far more to do with Jim Jones and Jonestown than the Republicans.
