This post has been updated to note that Perry has now officially gotten into the race for president.
Former Texas Gov. Rick Perry announced Thursday that he's running again for president. His 2012 presidential campaign was tripped up by back surgery medication and several embarrassing missteps, including his "oops" debate moment, in which he forgot the third federal agency he said he wanted to cut.
He has tried to get past that with a new look and better preparation this go-round. Here are five things to know about Texas' longest-serving governor:
1. Perry started his political career an Al Gore Democrat.
It's hard to believe now, but Rick Perry was a Democrat for five years when he first began as a Texas state representative in 1984. He admired Al Gore as a Southern centrist he could emulate and supported Gore's presidential campaign in Texas in 1988. It's a popular myth that Perry actually chaired Gore's campaign that year. Former U.S. Rep. Ron Paul ran an ad against Perry in his home state during the 2012 presidential race, charging that Perry was Al Gore's Texas cheerleader. (More on the cheerleader bit later.)
2. Perry was for big government projects before he was against them.
Interstate 35, which runs right up the middle of the state all the way to Canada was in desperate need of expansion. Gov. Perry came up with the Trans Texas Corridor — a superhighway, super train track, super everything that would transport people and goods to and from Mexico like nobody's business. The only problem was it was so wide it ate up half of Texas and rural landowners hated it. Conservative talk-show celebrity Alan Jones accused Perry of trying to create his own country out of the middle parts of Mexico, the U.S. and Canada. Perry denied it. The Trans Texas Corridor proposal eventually made like General Douglas MacArthur and faded away.
3. Perry tried to protect young teenage girls from cervical cancer.
To the surprise and delight of the state's Democrats, in 2007, Perry ambushed and bypassed the predominately Republican legislature by issuing an executive order mandating HPV vaccines for all 6th-grade public school girls. Liberals were puzzled but thrilled with Perry's "enlightened" order, while conservatives, especially the state's evangelicals were beside themselves. It turns out that Perry's former chief of staff, and longtime supporter, Mike Toomey, had become a lobbyist for Merck. And Merck made Gardasil, the vaccination which protects girls from the sexually transmitted cancer. And protecting hundreds of thousands of Texas's 6th graders would have required quite the batch. Indignant, the state legislature repealed Perry's order. During their 2011 presidential debate, Minnesota Rep. Michelle Bachmann accused Perry of "crony capitalism" because of this controversy. The accusation surprised and stung the Texas governor.
4. The two former GOP Texas governors — Bush and Perry — aren't big fans of the other.
It started in 1998 when Perry was first running for lieutenant governor and was in a very tight race with Democrat John Sharp. Perry's campaign wanted to run an attack ad against Sharp, but Gov. George Bush's man Karl Rove said, "NO!" Rove was in the midst of reelecting a very popular Gov. Bush in a sort of "compassionate conservative" campaign — laying the groundwork for Bush to run for president in 2000. Rove knew Bush had the governor's reelection in the bag, and he didn't want to alienate any Democrats with negative campaigning. Rove said if Perry ran the attack ad against Sharp, Bush would withhold his endorsement from Perry. So the Perry camp caved, didn't run the attack ad and barely squeaked out a win. There's been bad blood ever since. When Bush did run for president, Perry backed Rudy Giuliani instead and called Bush a profligate fiscal spender. It did not help smooth relations.
5. Rick Perry was a cheerleader at Texas A&M. Specifically, an Aggie Yell Leader.
At Texas A&M, the cheerleaders are all men as was the entire student body a long time ago. While cheerleaders at other academic institutions dress in colorful outfits and lead their fans in cheering the team, at A&M the Yell Leaders dress all in white and make large gestures while screaming at the fans. Thus the name. When a game is close they've been known to, well, squeeze their private parts so as to share the pain of the team on the field. It's serious business in College Station.
