Clinton and Rubio are in, airline headaches and Jordan Spieth's big payday

It’s a day of green arrows for the major indices with the Nasdaq (^IXIC) above 5,000 once again, the S&P 500 (^GSPC) bumping up against all-time highs and the Dow (^DJI) moving further above 18,000.

Here are some of the other stories Yahoo Finance is keeping an eye on today.

The race for the White House
It was Hillary Clinton yesterday…it’s Marco Rubio today. Clinton is now heading to Iowa to begin her run for President, which was announced with an online video Sunday afternoon. She’s the first Democrat to officially enter the race. Florida Republican Senator Marco Rubio has told donors he’s running and is set to make a more public announcement later this afternoon. He’s joining fellow GOP Senators Ted Cruz and Rand Paul.

Low wage jobs weigh on taxpayers
Certainly a topic that will be front and center in the 2016 campaign is worker pay. A new study finds low wages actually cost taxpayers $ 153 billion dollars a year. University of California at Berkeley researchers say that’s because so many of those lower-salaried workers also need government assistance programs to get by.

Stress in the sky
 Another study out today may come as no surprise–  airline passengers aren’t having a good time. The Wichita State Airline Quality Rating finds air carriers did worse last year in four key categories: on-time performance, involuntary denied boardings, mishandled baggage and customer complaints.

Jordan Spieth’s big payday
And finally…There will plenty of other green to go with the green jacket Jordan Spieth won with his impressive weekend performance at the Masters golf tournament. Golf Digest anticipates the 21-year-old Texan will earn at least $ 25 million dollars this year in winnings and endorsements–  putting him in the top 5 among all golfers.
