George P. Bush, Texas Land Commissioner and son of Jeb Bush, doesn't have all the same sour grapes as his father, and is asking Republicans to unify and vote for Donald Trump in the fall.

Though he has not formally endorsed Trump, he said to room full of Republican loyalists on Saturday that it's time to put down any lingering bitterness from the primaries and get behind all the GOP candidates in the fall.

“From Team Bush, it's a bitter pill to swallow, but you know what? You get back up and you help the man that won, and you make sure that we stop Hillary Clinton," Bush said to the room.

His calls for party unity were met with loud applause from the audience.

Bush is the Texas GOP's victory chairman, who has the job of overseeing the Republicans' statewide campaign in the Lone Star State, the Texas Tribune reports.

George P. could be playing the long game. He still has a strong future in politics -- many people predict he'll run for the White House in 12 or 16 years from now. He'd rather not have to go before millions of Republican primary voters and tell them why he couldn't get past his own personal feelings to stop Hillary Clinton.

Republicans back in 1964 faced a similar situation. Barry Goldwater was behind President Lyndon Johnson in the polls by 36 percent and was considered too extreme for the Republican establishment. Many elected officials including Nelson Rockefeller and George Romney refused to support the Arizona Senator.

Richard Nixon was one of the few who not only endorsed Goldwater, but campaigned for him across the country. His undying loyalty earned him support among the party's base despite the fact that he was much more liberal than them.
