The Republican debate on the Fox News Channel generated torrents of comment in social media for various reasons: the absence of frontrunner Donald Trump, who boycotted the debate, accusing Fox of not being fair to him; the battle between Ted Cruz and Marco Rubio for runnerup; and questioner Megyn Kelly's hair. Twitter followers were divided on the new short style, one calling it "scary awesome."

The winner in the February 1 Iowa caucuses may be none of those in the running. A new winter snowstorm moving from the Intermountain West is forecast for a large part of the central and northern Plains during Monday night and Tuesday.

While other candidates were giving their views on a variety of foreign and domestic issues on the eve of the Iowa caucuses, a petulant Donald Trump sought to satisfy his hunger for publicity by staging an impromptu fundraiser for veterans. Trump said the event brought in $6 million, which included $1 million of his own money. He set up a special website for donations, which were routed to Trump's private foundation. Sounds like something the Clintons might do.
