A symplectic principal bundle is a principal bundle $(X,B, G)$ with projection map $q:X\to B$ such that $X$ and $B$ are symplectic manifolds and the right action of $G$ preserves the symplectic structure of $X$. 1)Does this imply that $G$ admit a symplectic structure? 2)Under what conditions the following map preserves the standard Poisson Lie structures ? $$ T:C^{\infty} (X) \to C^{\infty} (B)\\ T(f)(b)= \int_{q^{-1}(b)} fd\mu $$ Here $\mu$ is the natural normalized Haar measure of the fibers of $X$.
