It says 'defeat' in pretty big letters, guys.
No it does not.
Yes they are.
Nice deflection from the insult to Democrats by the NRCC for their disgusting fundraising dishonesty.
You must have an extremely low standard for "reasonably literate". I fail to see how anyone who is literate enough to fill in the information needed to make a donation would miss that they were soliciting donations against the candidate.
In any case, I doubt the point of these sites is raise money directly. Rather, I think they are bait intended to entice some legal action against them which regardless of whether it is successful or not they can present to the base as evidence that "Obama and the liberal Democrats don't want people to learn the truth about <insert name here>. Please give generously to ensure that we can spread the truth about <insert name here> and defeat (him/her) this November."
