1.
The contemporary DNC and GOP parties are one party. the DeRps.

Ignore what they say, watch what they do!

Your common DeRp wants government spending and lots of it. DeRps don't care if they have to borrow it's only important that all of their choice interest groups (hobbies) are fed at the end of the day. The only difference between the DNC and the GOP is what the spending goes toward. They're consumers just like generation x women and no one takes their men seriously. The generation x women wear the pants in the DeRp house and they represent the marginal power of the DeRp vote.

If you're into programmed reality TV shows, the DeRps offer a lot of sibling rivalry intrigue for your interactive enjoyment.
Of, consisting of, or supported by members of two parties, especially two major political parties: a DeRp resolution.

Bipartisan is a code-word for “the kids are playing nice together.”
