Tim Canova's new TV ad attacking U.S. Rep. Debbie Wasserman Schultz accuses her of flip flopping on a few issues including fracking.

In an Aug. 14th debate on CBS4, Wasserman Schultz sounded open to fracking in Florida.

Host Jim DeFede asked: "So you are open to fracking as a possibility in Florida?"

She replied: "As long as we have significant regulations."

When the Miami Herald sent her spokesman a list of questions asking what type of regulations she wants, the campaign sent a statement saying she supports a state ban.

"Let me be clear, I am against fracking, especially in Florida," she said in a statement.

The ad also accuses Wasserman Schultz of flip flopping on medical marijuana, payday lending and Trans Pacific Partnership. Here is some background:

Medical marijuana: Wasserman Schultz opposed the 2014 state constitutional amendment but in this race says she is undecided about the similar amendment on Nov. 8th ballot. In May, she voted in favor of a measure to give veterans access to medical marijuana after opposing a similar measure in 2014.

Payday lending: Wasserman Schultz defended Florida's payday law which has been bashed by consumer groups and she pushed back against proposed rules by the federal Consumer Financial Protection Bureau. In June, she backed away from opposition to the new rules.

Trans Pacific Partnership: She voted to fast track TPP in 2015 but recently told the Sun Sentinel that she is still evaluating it.

Canova and Wasserman Schultz are competing in the Aug. 30th Democratic primary in a district that stretches from Weston to northern Miami-Dade County. The ad is running on cable and broadcast.
