Thompson is likely to launch his presidential bid in August.
WASHINGTON (CNN) – Former Tennessee Sen. Fred Thompson is now likely to announce his presidential campaign in August, not mid-July as previously envisioned and will skip the Republican straw poll in Ames, Iowa, people familiar with Thompson's thinking tell CNN.
The campaign-in-waiting is still being put together, and Thompson supporters say they want to have "100 percent" of the staff in place by the time of the announcement.
"Expectations are through the roof," said one source. "We have to match those at every level. . . . We have to be more ready than any of these other guys.”
Thompson created a state-level presidential exploratory committee in Tennessee in June.
