This just might have made sense when there were a lot of conservative Democrats out there whose votes we could pick up, but those days are gone.
A purer party in what way? I see a party where American loving democrats, republicans, independents and dis-engaged citizens fed up with both parties can participate and work together to reclaim our birthright. Both the Democrat and Republican parties are out of favor with the American public. They associate the whole bunch as self-serving corrupt greedy bastards. (and they'd be right)
