This was noticeably on display for me in 2020 right after it was determined that Biden had won the election. Lindsey Graham, a Republican Senator, was caught on video in the Senate chamber warmly congratulating and hugging Kamala Harris, a D senator and VP-elect. It was as if they both knew Graham's hyper-partisan antics during the preceding months before the vote was all just an act - a part of the game. I'd bet that he secretly voted for Biden/Harris as well and will do so again.
