LAS VEGAS (AP) - The first major test of billionaire Mike Bloomberg's presidential campaign is about to play out in Las Vegas.
He'll face questions and sharp elbows on a debate stage for the first time Wednesday night.
The rival campaigns of Bernie Sanders and Joe Biden started early, taking pre-debate shots at the former New York mayor.
It all shows how seriously Democrats are taking Bloomberg, now that he's rocketed to double-digit support in national polls and qualified for the next two debates.
He's built that support with $400 million in self-funded TV ads.
