The poll surveyed 500 people, evenly split between Democrats, Republicans and independents, with assets of $1 million or more. It found that Clinton is the top choice by a healthy margin, at 31 percent. Former Florida Gov. Jeb Bush (R) comes in second, at 18 percent.

The results could play into concerns from some liberals that Clinton is too close to Wall Street and not populist enough on economic issues.
