She needs to be replaced by an actual democrat.
How do you define "an actual democrat[sic]"?
Somebody who blindly follows directives from the party headquarters?
I would define an actual Democrat as one who adhere's to the national democratic platform. A small d democrat (which is how I'd describe Sinema, is one who follows the national platform as closely as possible, until it conflicts with the interests of the voters that they represent.
IOW, I think that it's a great mistake to attack local politicans trying to remain in office when they don't agree with an entire national platform. Politics is local. And democrats in Arizona, Oregon, and/or New York are not always in uniform belief. As a party, the dems are more numerous than republicans. However, we have less power. The reasons for this are numerous. But we can only overcome these differences by allowing a larger tent.
