The Dems haven't paid enough attention to cultivating new talent in the minor leagues.
They have too many designated hitters and not enough picthing and fielding.
Their designated hitters are so past their primes, they need pinch runners if they make base.
They keep blaming the umpires for their losses.

They keep getting caught using too much pine tar on their bats.

They like to yell "Balk!" on every GOP pitch.
