Ending Gridlock: When all Republicans agree with the Democrat position on an issue.
It's not that hard to turn a GOP Freshman to the dark side. The allure of the fancy cocktail circuits, the plum assignments, the lobbyists promising this and that pork spending for your district, and the corrupt GOPe putting their shoulders around you, "helping" you to "make the right choices", issuing threats if you make "the wrong choices", plus the opportunities to make lots and lots of money yourself!
Before long, you've become a loyal foot soldier for the statist cause, and your constituents are no longer the people in flyover country, they're the ones pulling the purse strings.
