A Suffolk University poll released Tuesday offers an encouraging sign for those in favor of allowing Florida's felons the right to vote.

Of 500 respondents across the state who were surveyed by phone from Oct. 25-28, more than 70 percent said they support Amendment 4, with about 21 percent opposed and 8 percent undecided. The measure would restore voting rights to felons once they have completed their sentences, with the exception of those convicted of murder or sexual offenses.

Florida is one of four states that disenfranchises felons permanently, along with Kentucky, Virginia and Iowa. If passed, Amendment 4 could affect 1.5 million Floridians.

Amendments require a super-majority of 60 percent to become law.

Poll respondent Cynthia Henry, a 54-year-old custodial supervisor in Quincy, said she's a staunch supporter of Amendment 4 because "people who serve their time — they don't have to pay for it the whole rest of their lives." She said she plans on submitting her mail-in ballot this week.

The poll also asked respondents about Amendments 3, 9 and 13, which are related to casinos, offshore oil drilling and vaping, and dog racing, respectively.

Results show 63 percent of respondents are in favor of Amendment 3, which would require voters to authorize any new casino gambling in the state but would not affect federal law regarding gambling establishments on tribal land.

Amendment 9, one of the bundled amendments, includes a ban on offshore oil drilling and a ban on indoor workplace vaping. The poll shows 46 percent of respondents in favor of the measure, with 35 percent opposed and nearly 19 percent undecided.

And nearly 51 percent of respondents favored Amendment 13, which would phase out commercial dog racing by 2020. Nearly 34 percent were opposed to that measure, with about 16 percent undecided.

Jim Ritchie, a 65-year-old semi-retired resident of Sebring, said he's voting no on Amendment 3 because it would "take gambling away from Florida."

Ramazan Dilek, a 37-year-old real estate broker in Boynton Beach, said he's particularly interested in Amendment 3 because he wants to make opening casinos harder. Dilek said casinos create problems and that he doesn't believe residents should lose their money to such establishments.

Dilek said the bundled amendments are "really bad" and that he'd prefer each proposal to be put up to a separate vote, adding that he supports certain aspects of the bundled amendments on this year's ballot but not others.

"It makes me feel like they're trying to cheat us," he said.
