Charles Bukowski - American author

so, this is my first time voting,
i have no clue on politics really,
been getting into it more.. supportive of obama.

well, i voted in the caucus awhile back,
and now i'm listed as a final delegate,
so i have to do some voting again this saturday.

i read a little on what a delegate is,
but can anyone give me a more simple break down
of when a delegate is and does?

i'm trying to get more informed online also before saturday.

thanks.
