Conclusions

One would hope that this joint pre-GOP convention event held at River Church indicates that everyone is finally abandoning the myth that the Tea Party is separate from the Religious Right, or that it has a completely different agenda, as well as the myth that the Tea Party movement is nonpartisan. However, after watching live-streaming of this event for five hours, I would conclude that the right flank of the GOP is not particularly happy with the Republican Party hierarchy right now. They are also not very excited about Mitt Romney and will try to motivate voters based on fear and their animosity toward President Obama.

Also see coverage of the event in The Nation. The LA Times provides the following additional information.

In the lobby of the church, several groups handed out literature and hawked conservative-themed merchandise. The most eye-catching of the works was by painter Jon McNaughton. It showed a shadowy Obama figure holding copy of the Constitution, set aflame. In the flames the word "obey" appears and, in the crumpled document, one can discern a hammer and sickle -- symbol of the old Communist Soviet Union.

The print, a part of McNaughton's "Nation Under Socialism" series -- sold for $69. The artist's work comes highly praised in the eyes of the tea party crowd -- recommended by Sean Hannity and mocked by Stephen Colbert.
