Leid Stories--It's showtime in Las Vegas-02.19.20

It's showtime in Las Vegas tonight as Republican-turned-Democrat Michael Bloomberg makes his much-anticipated debut in the Democrats' 2020 presidential beauty contest. 

Bloomberg will be facing off against former vice president Joe Biden, an early favorite now trying to bounce back from from near-lethal "gut punches;" former South Bend, Ind., mayor Pete Buttigieg, running a tight race against Sen. Bernie Sanders of Vermont, who almost stopped him in Iowa; Minnesota Sen. Amy Klobuchar, a moderate enjoying a small burst of support but far from winning;  and Massachusetts Sen. Elizabeth Warren, a progressive whose promising campaign has suffered some major setbacks.

What do you think voters would be most interested in hearing the candidates' positions on? What issues do you expect will dominate tonight's Q&A session?
