Sarah Palin is getting back on the campaign trail. She'll hit the road this Friday at an evening rally for Ted Cruz, Texas candidate for the U.S. Senate, at the Woodlands, north of Houston, his campaign and a Palin friend confirmed for ABC News.

Palin appeared at an Americans for Prosperity rally earlier this month in Michigan, but she hasn't been out and about recently in support of candidates she has backed. During the 2010 midterms, she went on tour with the Tea Party Express, making stops throughout the country on behalf of Tea Party candidates.

And it's not just Palin. South Carolina Sen. Jim DeMint will also be on hand for the 6 p.m. rally. Glenn Beck will be featured at another rally Thursday at the American Airlines Arena in Dallas and Rick Santorum will be campaigning with Cruz over the weekend, although the details are still being worked out.

This Friday begins the final weekend before the Texas Republican Senate runoff. Tuesday, Cruz faces off against Lt. Gov. David Dewhurst for the seat being vacated by Sen. Kay Bailey Hutchinson. Dewhurst, a former solicitor general of Texas, is backed by Gov. Rick Perry and was once considered a shoe-in until Palin and other conservative favorites got involved in the race.

Cruz's communications director James Bernsen said they expect large crowds at both the events in Dallas and Houston. Bernsen told ABC News that after Palin's endorsement before the May 31 primary they received between 900 and 1,000 online donations almost immediately. A huge boon to their campaign.

The former Alaska governor has a stellar GOP primary endorsement record so far this cycle. She backed Orrin Hatch in his Senate primary in Utah, Richard Mourdock in his primary against Dick Lugar in Indiana, and helped Deb Fischer with her surprise victory in Nebraska. She still has not formally endorsed Mitt Romney nor joined him on the campaign trail.

The Texas senate race is the most expensive in the country so far this cycle, with more than $37 million spent so far. Dewhurst spent $11 million of his own money alone.

News of Palin campaigning with Cruz was first reported in the National Journal.
