On Tuesday, Nevada will hold a Republican presidential primary. Two days later, the state GOP will host Republican presidential caucuses — with a different set of candidates competing. President Biden won the Democratic primary in South Carolina on Saturday, notching a decisive victory in his party’s first official nominating contest. Former president Donald Trump holds the lead in the Republican delegate count.

President Joe Biden pitched for votes Sunday in Nevada, where the first-in-the-West primaries are underway with early and absentee voting. But the Democrat and his team are also using the visit to shore up support for the general election in November.

When the Kansas City Chiefs and the San Francisco 49ers face off at Super Bowl LVIII on Sunday, Feb. 11, they will compete for football's highest honor at Allegiant Stadium in Las Vegas. It was unthinkable because, for many years, professional sports teams, including the NFL, refused to go anywhere near Las Vegas, thanks to its seedy reputation.

Take Las Vegas and the NFL, add the world's hottest pop star, a love story that has social media spinning like a slot machine, two superb teams and you get what might be a landmark Super Bowl cementing Sin City's status as a global sports hub.

The perception of Las Vegas has shifted dramatically. As much as it remains known for gambling, nightlife and over-the-top entertainment, it’s now a major player in the sports world, featuring the NFL, NHL, WNBA, UFC and boxing.

In late 2002, a marketing firm trying to reinvent Las Vegas believed it had captured the allure of the city in a commercial worthy of the Super Bowl.

Voters see an uncompetitive primary. Team Biden sees an opportunity.
