A majority of Americans... polled by CNN...
The meme is actually about the tendency of the DNC (that's the Democrats) to ignore the votes of their own constituents. Proving that the opposite party (the Republicans) are corrupt would by no means exonerate the Democrats. To try and say the Republicans are corrupt because they haven't removed an elected official (whose approval ratings just hit his personal best) is incredibly absurd.
Thanks for the comment though.
