Former President George H. W. Bush will formally endorse Mitt Romney on Thursday in Houston. 

The endorsement comes a week after one of the former presidents sons, former Florida Gov. Jeb Bush (R), endorsed the GOP front-runner. Former first lady Barbara Bush has also endorsed him.


In December 2011, the elder Bush indicated his support for Romney, calling the former Massachusetts governor the best choice for us.

The endorsements by most members of the Bush family suggest mainstream Republican heavyweights want the Republican primary to effectively end, and for the party to rally around Romney. 

In his endorsement last week, Jeb Bush urged the party to unite around Romney. 

Primary elections have been held in 34 states, and now is the time for Republicans to unite behind Gov. Romney and take our message of fiscal conservatism and job creation to all voters this fall, the former Sunshine State governor said in his endorsement.
