A guide to Florida's primary election

(AP) — Florida voters will select Tuesday the nominees for U.S. Senate, decide whether to amend the state constitution to give a property tax break to promote solar energy and have a say in who should represent them in the U.S. House.

Murphy wrapped up major endorsements early in the campaign and is the establishment favorite to try to win back Sen. Marco Rubio's seat as Democrats try to regain a Senate majority.

Grayson has a reputation for being a fiery, outspoken liberal who isn't afraid to break political norms.

Grayson has been dogged by ethics allegations over an offshore hedge fund he managed and a claim by the mother of his children that he abused her over two decades.

Sanders endorsed Canova, leading to a flood of donations from outside Florida in what appears to be an effort to take revenge at the party establishment for the way the presidential primary was handled.

Canova has raised about $3.3 million — more than Wasserman Schultz and an astounding amount for a first-time candidate running against someone who has served the area for more than 24 years in the state Legislature and Congress.

The state Supreme Court ruled that lawmakers violated a voter-approved constitutional amendment requiring districts to be drawn in a compact manner that doesn't favor incumbents or political parties.

Voters will decide on a ballot measure to provide property tax breaks for people who install solar panels on their homes.

The increased value to a home from the installation of solar panels or other renewable energy devices can't be considered when assessing homes to determine property taxes.
