Reince Priebus is the Chief of Staff for President-Elect Donald Trump for his new administration. Priebus's appointment disappointed some Trump supporters, who consider him to be part of the Establishment.
Priebus has been a RINO Backer who was elected to be the Republican National Committee chairman in 2011, and then led the Republican Party to one of its worst performances in history: instead of winning the Senate as expected, the Republican Party lost seats there, and an incumbent Democrat was reelected president despite high unemployment.
Priebus has never been elected to public office. He was formerly the head of the Wisconsin GOP, and then the RNC.
Priebus was reelected as Chairman of the Republican National Committee in early 2015 after Republicans scored historic gains in the 2014 midterm elections, where were due to opposition to ObamaCare and fears about the Ebola outbreak coming into the United States.
On election night, Trump credited Priebus for his campaign efforts, but post-election analysis showed that Trump's victory in Priebus's home state of Wisconsin was not due to a get-out-the-vote effort, but to substantially lower turnout by Dems to vote for Hillary Clinton.
Humorously, Reince Priebus's consonants in his name spell "R.N.C. P.R. B.S."
Priebus reportedly had a role in promoting pro-choice nominee Neil Gorsuch to the U.S. Supreme Court, and Priebus may have assured Trump that Gorsuch would be confirmed by the Senate. Instead, the Dems filibustered Gorsuch, and Mitch McConnell resorted to the nuclear option to change the Senate rules and forever end the filibuster rule in the U.S. Senate for judicial nominations. This wasted all of the political capital of the Republican Party and left the Dems more determined to block future legislation.
