The moonbats actually have a plan here: Sheehan's role is to make Pelosi look centerist.
Yes!
The Left has traditionally used its most extreme to make the average wacko nutjob moonbat seem 'normal'.
Rather than use our own 'extremists' on the Right the same way, we keep throwing them under the bus.
This has forced the continuous morphing to the left which has occurred in the last few decades to appear within the realm of 'normal'.
Which has lowered the conservative bar--a lot.
