1. Sarah Palin was in Iowa today -- not for electioneering, but for the premiere of Undefeated, a new documentary about her. Outside the Pella Opera House, she refused to elaborate on her daughter's statement on Fox and Friends yesterday that her mother had "definitely" made up her mind about whether she will run.
"What exactly did Bristol say?" she said. "I texted Bristol, I said 'What did you say this morning, honey?' What I told Bristol, too, I said, 'What is talked about on the fishing boat stays on the fishing boat.'"
She also said that she is "not ready to announce anything yet" about a possible candidacy.
2. Speculation continues, too, about the intentions of Texas Governor Rick Perry. He will be in California this week, holding private meetings with Republican leaders, potential fundraisers and legislators.
Tomorrow morning, he will meet with business leaders in Beverly Hills, a city which is a rich source of campaign funding. Later, he will meet with GOP leaders in Newport Beach, before meeting Republican legislators in Sacramento.
While a spokesman says that the trip has nothing to do with the 2012 campaign, this programme of meetings appears to say otherwise.
3. Michele Bachmann has styled herself "American Girl" of the presidential race, as the grassroots Tea Party candidate, and used the 1977 hit song at the end of two speeches this week in Waterloo, Iowa, where she formally kicked off her campaign. But if reports are to be believed, she won't be able to use it as her theme for long. According to the Los Angeles Times, Tom Petty has told Bachmann that he doesn't want her to use his song at campaign events.
She is not alone -- Petty was also reported to refuse George W Bush's request to use his song "I Won't Back Down". If you are still in any doubt about the singer's political orientation, Hillary Clinton used "American Girl" at events when she was running for the Democratic nomination in 2008. Petty did not object.
4. The Democratic super PAC Priorities USA launched a television advert today in Colorado, Florida, Iowa, North Carolina and Virginia (states thought to be competitive in the next election), rebutting claims made in an ad by Crossroads GPS, an independent conservative group founded by Karl Rove.
The $5m Crossroads ad -- released on Monday -- blamed President Barack Obama for the unemployment rate, national debt, and high gas prices.
The Priorities USA ad, which by contrast cost in the region of $750,000, calls this "politics at its worst".
5. Herman Cain, the Republican presidential candidate, will publish a book detailing his life and career as the former CEO of Godfather's Pizza.
The memoir will be called Who is Herman Cain? and is set for release in October.
A statement released by the publisher said:
The recent Republican debate in New Hampshire introduced Herman Cain as a Presidential candidate, yet little is known about his impressive background. A proud 'outsider' in the political arena, Cain created his name in corporate America rather than on Capitol Hill, through four decades spent revitalizing business in the private sector.
Unfortunately, he is still polling in low single-digit numbers, though.
