For the second time in the past week a poll shows former Miami Beach mayor Philip Levine leading the race for the Democratic nomination for governor. The survey also shows gun violence is on the top of minds of Democratic voters heading into the 2018 election season.

The poll, which was obtained by the Miami Herald, was conducted by Public Policy Polling (PPP), a North Carolina firm that leans more Democratic. It shows Levine on top with 22 percent of the Democratic voters surveyed followed by Gwen Graham at 19 percent,  Andrew Gillum is at 8 percent and Chris King at the bottom of the list with 5 percent. A large number of voters, 46 percent, remain undecided.

Levine also leads Graham in favorability ratings. Twenty-nine of the Democrats surveyed give Levine a favorable rating compared to 15 percent for Graham.

The survey of 613 likely Democratic voters was conducted between March 23-25.

A survey released a week ago by Gravis Marketing showed Levine leading Gillum 13 percent to 11 percent.

The PPP poll released Tuesday also shows what issues are of most importance to Democrats in this year’s election cycle. The poll suggests the school shootings at Marjory Stoneman Douglas High School in Parkland last month has reshaped views of Democrats when it comes to gun violence

Thirty-one percent of the Democrats surveyed, nearly one in three, who are likely primary voters say gun safety reform is the most pressing issue of the election for them. That’s followed by healthcare, which usually tops the list of issues among Democrats, with 26 percent of those surveyed and public school funding with 13 percent.
