When Scott McInnis appeared on Fox News last month underneath a title calling him the "Tea-Party-backed candidate" for governor, he triggered a tempest. Tea Party leaders fired off angry e-mail messages and public statements insisting that he was not their choice.
"Let it be known that we will not be used by any party or candidate!" Lu Ann Busse, the head of a coalition of Tea Party brethren known as 9/12 groups, declared at a "Defend the Republic" rally where she was invited to set the record straight after Mr. McInnis's appearance.
Mr. McInnis said it was Fox that gave him the description without consulting him. But he was quick to try to make amends, issuing a statement on his Web site, and in the weeks since he and the head of the state Republican Party have toured Colorado meeting with Tea Party groups.
Across the country, many Tea Party activists believe that they have to work within the Republican Party if they want to elect fiscally conservative candidates. But they want the party to work for them - not, they argue, the other way around.
For Republican officials, managing the tensions between the two parties - one official, one potent - can be something like a full-time job.
"I do spend a lot of my time running interference," said Dick Wadhams, the chairman of the Colorado Republican Party.
"I'm a big believer in the Tea Party groups," he said. "I'm not going to claim that every Tea Party or 9/12 leader thinks I'm hunky-dory, but I do think the people who I've reached out to would acknowledge that I've welcomed them into the Republican Party. It's a big priority of mine."
Some Republican Party officials say privately that they are not yet certain whether the Tea Parties will prove to be a real force or simply the loudest voices. But the Tea Parties have proven their populist rage can be a power, whether to destroy Republicans - driving one out of a special Congressional election in upstate New York - or elect them in the most surprising of places, like Massachusetts.
So publicly, Republicans are trying to make nice with Tea Party groups, particularly in states like California, Colorado, Florida, Kentucky and New Hampshire, where Tea Partiers are upending Republican unity with primary challenges to establishment candidates.
