TAMPA, Fla. (AP) — Supporters of the medical marijuana Amendment 2 have begun a movement to build grassroots support to the cause, but opponents note the group is still funded by a multimillionaire.

The Tampa Tribune (http://bit.ly/1nvkvND ) reported that “Yes On 2” have asked supporters to donate a small amount every time opposing “Vote No On 2” posts on Facebook or Twitter. The amount can be as little as 50 cents.
