(CNN) - Close ties between two of the Newt Gingrich's departing senior staffers and Texas Gov. Rick Perry are fueling speculation about a potential Perry presidential campaign.
Gingrich staff members Rob Johnson, who was the former House Speaker's campaign manager, and David Carney, a Gingrich senior adviser, are two of Governor Perry's top political confidantes.
Their resignation from the Gingrich presidential campaign now frees them to assist Perry should he decide to seek the GOP nomination.
Perry recently said he plans to consider a presidential bid after the Texas legislative session concludes.
One Republican told CNN that while a potential Perry candidacy was not the cause of the Gingrich resignations, it might be the effect.
A senior GOP strategist told CNN's Chief Political Analyst Gloria Borger that some of Perry's top donors have been calling around Washington this week asking what Perry should do.
Meanwhile, a Perry adviser in Austin said Johnson and Carney "can now talk to the rest of" Perry's advisers "where they couldn't before."
"Nobody could have discussions because they were working for Newt," the adviser said.
The adviser added, "There have been no decisions or happenings in Texas concerning Gov. Perry. There's been no meetings, no discussions [among Perry's inner circle]."
Despite the 2012 buzz, Perry's office continues to insist that the governor has no current plans to run for president.
Perry's communications director Mark Miner stated the obvious. "There is no campaign," he said.
Miner called Johnson "a key player" in Perry-world but said there have been "no discussions that I am aware of" between him and the governor about a possible campaign.
Asked about Perry's interest in the White House, Miner told CNN that the governor "has been very consistent in saying that he is thinking about it, like he is a lot of things these days."
Miner dismissed talk of a shadow campaign being organized by donors and other Perry supporters.
"There are people that think they know what is going on, but they don't," he said.
