LAS VEGAS (CBSNewYork/AP)Former New York City Mayor Michael Bloomberg said he will “think about” whether to endorse either of the two presidential candidates likely to face off in the November election, Donald Trump and Hillary Clinton.

The billionaire said, “I’m not sure what I’ll do.”

But he said only three of the candidates this year had the skills to “run the railroad” as president: Jeb Bush, John Kasich and Clinton.

Bloomberg earlier this year decided not to pursue the White House as an independent, and in announcing that decision blasted Trump for running “the most divisive and demagogic presidential campaign I can remember.”

“As the race stands now, with Republicans in charge of both Houses, there is a good chance that my candidacy could lead to the election of Donald Trump or Senator Ted Cruz. That is not a risk I can take in good conscience,” Bloomberg wrote in an op-ed on Bloomberg View in March.

He continued, “Threatening to bar foreign Muslims from entering the country is a direct assault on two of the core values that gave rise to our nation: religious tolerance and the separation of church and state. Attacking and promising to deport millions of Mexicans, feigning ignorance of white supremacists, and threatening China and Japan with a trade war are all dangerously wrong, too. These moves would divide us at home and compromise our moral leadership around the world. The end result would be to embolden our enemies, threaten the security of our allies, and put our own men and women in uniform at greater risk.”

Bloomberg now said he will spend “nowhere near as much” donating to the presidential campaigns as he will on down-ballot matchups. He has tended to back mostly Democrats as he focuses on issues such as gun control and stopping climate change.

Bloomberg’s name popped up on the 2016 radar following reports he would consider running if Trump or Cruz took the Republican nomination and if Sen. Bernie Sanders beat Hillary Clinton on the Democratic side.

Bloomberg was making the comments Wednesday at the SALT Conference of finance industry leaders being held in Las Vegas.
