Washington (CNN) - Former Iowa Gov. Terry Branstad formally announced Thursday that he will try to get his old job back in 2010.
The Republican, who served four terms as governor of the Hawkeye State from 1983-1999, officially joined the race via Twitter. He said he will kick off his campaign with a four-day, statewide tour of 17 cities from January 19-22.
"This tour is just the beginning," Branstad said in a statement on his campaign Web site. "I plan to visit all 99 counties, just as I did as governor. I look forward to meeting with Iowans as we discuss my positive vision for leading Iowa's comeback."
Branstad's competitors for the Republican nomination are businessman Bob Vander Plaats and State Reps. Rod Roberts and Rep. Chris Rants. The winner will face Democratic incumbent Chet Culver.
Most recently, Branstad was the president of Des Moines University, but resigned to explore another run for office. While he served as Iowa's governor, he was the chairman of the National Governors Association in 1989 and of the Republican Governors Association in 1997.
