Texas Sen. Ted Cruz, a darling of the Tea Party and conservative movement, has agreed to write a personal memoir about his controversial days in Washington and his vision for the future for HarperCollins, according to publishing sources.

The first term Cruz is expected to receive an advance close to $1.5 million after a four-day book auction last weekend, easily winning the authorship primary over several others penning pre-presidential primary books including Florida Sen. Marco Rubio, Kentucky Sen. Rand Paul, and Wisconsin Gov. Scott Walker.

The advance would be the biggest for a conservative politician in years, even more than the $1.25 million that former 2008 GOP vice presidential nominee Sarah Palin received after her sensational rise in Republican politics.

The deal was negotiated by Keith Urbahn and Matt Latimer of Washington-based literary and communications firm Javelin. They also cut recent deals for former Defense Secretary Don Rumsfeld and CBS investigative journalist Sharyl Attkisson.

The book, still untitled and unwritten, will be part memoir and part Cruz's view of how to get Washington to work again as well as his vision of the future for the country. The 43-year-old has quite a story to tell, being the first Hispanic to serve as Texas solicitor general and as Texas' senator. Elected in 2012, he has also been in the middle of several major fights in Washington, including last year's government shutdown and the continued efforts to repeal and replace Obamacare.

Several publishing giants fought over the weekend to grab the Cruz book before HarperCollins emerged the winner. A final deal has not been signed but is expected in the coming weeks. The other publishers included St. Martin’s, Simon & Schuster and Newsmax.

The fight was the first big one where Newsmax, the popular center-right news website started by journalist Chris Ruddy, played in. Sources said Newsmax also offered a bid of $1 million or more.

Cruz has recently been making trips to key presidential states, raising his profile nationally as well as his call that conservatives stand on principle and not give in to Democrats just for the sake of compromise.
