The Note: Your 2016 Weekend Speed Read

— -- NOTABLES

--Scott Walker: "Cutting taxes is like shopping at Kohls -- using coupons and discounts, you get shirts for dirt cheap instead of market price. Kohl's knows that you can sell a few full-price or a lot for less. Same with the economy -- the more you lower taxes on people, the more people engage in the economy."

--Carly Fiorina: "Like Hillary Clinton, I'm also running for president, but unlike her, I'm not afraid to answer questions about my record. She's answered 7 on the record questions since April 12th, I've answered over 200 on the record since Monday."

--Donald Trump: "I'll be making a decision very soon, I think a lot of people will be very happy, and some of them will be very surprised."

WHAT WE'RE WATCHING

BETTING ON HILLARY: WHAT THE ODDSMAKERS ARE SAYING. The U.S. presidential election is a year and a half away and already thousands of people around the world are putting money on who they think will win the race -- but not in Las Vegas. Due to a federal law, it's illegal in the United States - and yes, even Nevada - to bet on any elections, national or local. Some in Nevada, including longtime sports bookie and head oddsmaker for the South Point Casino in Las Vegas, Jimmy Vaccaro, are hoping to change that. "It would be a boon for the state of Nevada if you could bet nationally," he recently told ABC. Opponents of betting on elections fear that if it were legal it could lead to issues of rigging or could encourage people to vote based on who they put money on instead of who they actually want to win. Vaccaro, however, said he believes presidential elections are simply "too big" to rig, and said legalizing election betting could alter voter turnout in a good way.

ISIS PUSHING US INTO 'NEW ENVIRONMENT' IN THREATS AGAINST HOMELAND, HOMELAND SECURITY SECRETARY SAYS. The effective use of social media by the terror group ISIS has thrust the U.S. into a "new environment" when it comes to the threat against the homeland, DHS Secretary Jeh Johnson said yesterday on "This Week." "We're definitely in a new phase in the global terrorist threat where the so-called lone wolf could strike at any moment," Johnson told ABC's MARTHA RADDATZ. "It is a new environment, but we are not discouraging Americans from doing the things they do on a daily basis." Johnson said state and local law enforcement agencies need to be vigilant about possible threats and noted that he has ramped up communication between DHS and local law enforcement over the past 16 months, according to ABC's STEPHANIE EBBS. But when asked whether local communities are doing enough, Johnson said some agencies are "still a work in progress" and stressed the importance of engagement from within the Islamic community http://abcn.ws/1KVksYU

TODAY ON THE TRAIL with ABC's CHRIS GOOD: Scott Walker is in Israel, where he donned a yarmukle yesterday and visited the Western Wall. Walker has said he is planning to meet with Netanyahu on the trip. Rand Paul hosts a town-hall at the Londonberry Lion's Club in Londonberry, N.H. Mike Huckabee speaks at The Houston Club in Houston.

MICHELLE OBAMA: 'STING' OF RACISM 'DIDN'T HOLD ME BACK.' During a passionate address at historically black Tuskegee University over the weekend, Michelle Obama said she refused to let the "sting" of racial bias define her, ABC's ERIN DOOLEY notes. "Over the years, folks have used plenty of interesting words to describe me. One said I exhibited a little bit of 'uppityism,'" the first lady said. "Cable news charmingly referred to me as 'Obama's baby mamma.' "All of the chatter, the name-calling, the doubting, all of it was just noise," she said. "It did not define me, it didn't change who I was, and most importantly, it couldn't hold me back." http://abcn.ws/1KvRqyq

SEN. RICHARD BURR DEFENDS BULK PHONE RECORD COLLECTION. With key provisions of the Patriot Act set to expire, Senate Intelligence Committee chair Richard Burr yesterday defended the federal government's bulk phone-record collection. Congress is set to debate the future of the Patriot Act this month, and much of that debate will focus on the law's controversial Section 215, which the government has for years used to gather Americans' phone records in bulk. "I think it's very effective at keeping America safe," Burr, a Republican from North Carolina, told ABC's MARTHA RADDATZ. Burr recently introduced a bill with Senate Majority Leader Mitch McConnell, R-Kentucky, to reauthorize Section 215's current language when it expires June 1.  http://abcn.ws/1FXxrcK

FORMER PRESIDENT JIMMY CARTER LEAVES GUYANA AFTER FEELING UNWELL. Former President Jimmy Carter Sunday left Guyana, where he had traveled to act as an election observer, after complaining that he felt unwell. The Carter Center issued a statement saying he was returning to Atlanta and cutting his election observation visit short, ABC's BEN CANDEA reports. The statement didn't specify why Carter, 90, left, only saying he was "not feeling well." "President Carter is hopeful about Guyana's election and expressed his commitment and that of The Carter Center to supporting Guyana in the days ahead, stressing the need for a peaceful process before, during, and after the election," read the statement. http://abcn.ws/1Ky8PX8

IN CASE YOU MISSED IT

SURPRISE PHONE CALLS FROM PRESIDENT OBAMA LEAVE MOMS SPEECHLESS. Most moms hope to get a hug or a call from their kids on Mother's Day. What they definitely don't expect is a call from the commander-in-chief. But President Barack Obama decided to make this Mother's Day a holiday three American moms would never forget. All three women had written letters to Obama and were reportedly told to expect a call on Wednesday from a White House official. When they heard the president's voice on the line, they could hardly believe their ears, ABC's ERIN DOOLEY notes. http://abcn.ws/1F7ilRg
