His spokesman explained to the Austin American-Statesman: “In the final weeks of the campaign, a better use of the governor’s time is to continue traveling the state talking to Texans about issues that are important to them.”
Frankly, Perry didn’t have a lot of use for the media — not after two terms as governor — nor did the media have much use for him, as most major papers endorsed his GOP rival in the gubernatorial primary and Democratic rival in the general election.
He further enraged the media when he spoke at a national editorial writers gathering last fall and wouldn’t take questions, prompting the group’s “stunned” president to send Perry a letter accusing of him of “disingenuousness” and going back on his word.
The fact is, Perry was so far ahead that he didn’t need the press, and he romped to a huge win in his reelection bid. Source
His 2010 reelection campaign was based on Bush 43's 2004 reelection campaign strategy that was organized by Carl Rove. The campaign got volunteers to set up "home headquarters," and each volunteer who set up a "home headquarter" would agree to contact 11 friends. It's a very decentralized campaign that bypasses the media. Some of the people hosting "home headquarters" were celebrities such as Troy Aikman, David Barton, Rudy Giuliani, Mike Leach, etc.
