This article explains succinctly why Senator Hatch decided to retire. 

His donors have been fully paid off, he’s 83, and public opinion in Utah is against another term for him.

“After 41 years in the U.S. Senate — a blink really — Orrin Hatch, R-Utah, is retiring at the age of 83. He ran on term limits in 1976, zinging his opponent with, “What do you call a Senator who’s served in office for 18 years? You call him home.” Now a government career older than the Seattle Mariners comes to a close. Sometimes they’re gone before you know it.

“Goodness knows what Hatch will do now. But what is even less certain is what the Republican Party will do without him and over two dozen peers; he’s not taking the sunset trip alone.

“Although “shepherding the GOP tax reform bill through the Senate” already represents an ignoble enough swan song to close a career, Hatch’s reason for leaving might be even less dignified than that. Polls show 75 percent of Utahns don’t want him to run again, perhaps because of his 2012 pledge not to seek another term.“

Time for Senator Hatch to stay home after serving as Trump’s faithful lapdog.

Amazing how many Republicans have decided it’s time to spend more time with their family. Hatch is likely to be replaced by Mitt Romney, who is well liked in Utah, having successfully run a Winter Olympics there and being a Mormon.

Many others, perhaps, may be hearing the sound of a big blue wave, the one that started in Virginia.
