Still, he doesn't begrudge the Phillipses for claiming that his Nashville event is a national affair.
"I mean, a name is just a name. It's just a marketing thing," Robertson said Wednesday from his home in East Texas.
The out-of-work engineer won't be attending the convention this weekend. He said he simply can't make the trip, but he will be there in spirit.
Robertson does, however, have a major problem with the keynote speaker.
"She hasn't been a part of this movement at all and she doesn't seem to be suffering at all," he said, "as [have] many of these patriots who've been donating their time, their money and their resources."
To Palin's claim that she'll be returning any money she receives "to the cause," the founder of teaparty.org, who eschews the political establishment, scoffed.
"But she's giving money back to the machine, right?" he asked. "Republicans."

Delegate William Temple from Georgia, who was dressed in a kilt, said he wanted to work against "Republicans, Democrats and Independents who have been in Congress too many terms."
"We're sick of everyone," he said.
However, when pressed, Temple said he could not ever remember voting for a Democrat.
Jim and Julie Dam drove five hours from Indianapolis to be at the convention. They said their biggest fear is the spending that comes out of Washington. But they said they wanted to work within the Republican Party to reach their aims.
"I'm not interested in a third party," Julie Dam said. "My husband isn't either."
"We want conservative Republicans," Jim Dam said.
