A new poll shows that Proposition 15, the property tax increase initiative on the November ballot, is losing popularity with likely voters.

A Public Policy Institute of California (PPIC) poll released September 17 showed that voter support for Proposition 15 is barely above 50 percent and has fallen in recent months. The PPIC poll found that even after being subjected to more than a year of misleading campaigning by public employee unions, only 51 percent of likely voters say they support Proposition 15, while 40 percent are opposed. The margin of error is plus or minus 3.5 percent.

Support has fallen by two percentage points since the PPIC asked a split-roll question in April.

The poll was taken from September 4 through September 13. The Yes on 15 campaign launched a television ad campaign two days before the PPIC began polling, while the No on 15 campaign launched its television ads (“Barber Shop” and “Wrong Time”) on September 8, midway through the polling.
