Rick Perry launched his presidential campaign with a headline-filled week on the stump. Sarah Palin is still undeclared, but seemingly giving it serious thought.
Her most recent move -- a video released by SarahPAC reprising her trip to the Iowa State Fair earlier this month -- looks a lot like a campaign commercial. She'll also be returning to Iowa Sept. 3 to headline a Tea Party rally.
Perry and Palin have known each other since before the 2008 election and they've both sung the other's praises over the years, but whether their relationship is close enough to stop Palin from getting into the race remains to be seen.
A Republican strategist with knowledge of Palin's thinking says they are close. "At the principal level, the relationship between Gov. Rick Perry and Gov. Sarah Palin is very warm," the source said.
Their "excellent relationship" notwithstanding, the source said, there's no way it would stop the former Alaska governor from jumping in the race.
"It wouldn't stop her, certainly if she is planning on running Perry's entrance wouldn't stop her because everyone knows that as soon as she enters, she'd be a top-tier candidate," the source told ABC News.
Sources close to Palin say even her closest advisers do not know what her decision is or even whether she has made one.
The last time the two met in public was in November at an anti-abortion rally in Dallas. Both politicians echoed many of the same themes, with Palin calling the Obama administration-backed health care law "horrendous" and Perry telling an audience of several hundred that the federal government "continues to undermine the laws that prevent funding for abortions."
The two spent time together at that event, but it's unclear whether they have talked since then.
Mark Miner, a spokesman for Perry's presidential campaign, declined to say whether Palin and Perry have spoken to each other in recent weeks, saying that the campaign would not comment on the governor's private conversations.
Steve Bannon, the man behind "The Undefeated", the pro-Palin movie that details her political rise in Alaska, cautioned not to read too much into the relationship between Perry and Palin.
"I think that when you talk about friendships between any political leaders it's all, that's all overblown," Bannon said. "People are cordial and people like each other personally, but I think, particularly in a crisis like this, it's about what your program is and how your program is consistent with this core set of values.
Despite Palin's support for Perry in the past, Bannon added, Palin's history in Alaska of exposing corruption and ethics reform -- a record that is highlighted in "The Undefeated" -- might not mesh well with criticism that Perry has consistently rewarded political donors with state appointments.
"I think you can tell from her time in Alaska and what she said in the rise of the Tea Party that she is very concerned about the influence of money in politics and the issue of crony capitalism," Bannon said.
Palin spoke about Perry on both legs of her bus tour. On the first leg in Baltimore, she praised the Texas governor, saying she thought he would make a "fine candidate" and the two "have a lot in common."
Palin added, "I really like him."
