What's with many Democratic Party leaders supporting people who support people who support destroying the Democratic Party?

I'm going to steal a page out of Diane Ravitch's blogging book (stylistically).

I'm still having a hard time understanding education reform politics.

I do not understand how Democrats and progressives put up with self-proclaimed liberals and liberal groups such as Michelle Rhee, Joel Klein, StudentsFirst, Stand for Children, and Democrats for Education Reform.

I wrote about this before, although not as directly as I am going to here.

All of the afore-mentioned groups and individuals either give money to or make money for or support Republican politicians and organizations. See here, here, here, here,  here, here, and here.

These candidates are anti-women's rights, anti-gay, and anti-immigrant.

So Campbell Brown wants to help protect students from teachers who are sexual predators and who are protected by unions (just for the record, I believe that is anti-union propaganda). Okay. But what if a teacher has sexual intercourse with a student (which I agree is a fireable if not criminal offense) or if a student is raped by a teacher and then gets pregnant? Campbell Brown's husband (Romney adviser Dan Senor) and Michelle Rhee (who Scott supports) give money to or want to elect some people who belong to the party that would force the targeted/raped student who got pregnant to have the teacher offender's baby.

Also, they are working to elect people who don't accept homosexuality and don't want to protect homosexual students from bullying.

And, they are endorsing anti-immigrant candidates.

And what about the threats that GOP-endorsed legislation poses to voting rights?

On what planet does it make sense for the DNC and high-profile Democrats, such as Barack Obama, to support these groups and people? How is it that they get to call themselves Democratic allies and liberals when they are actively supporting people who want to destroy the Democratic Party and dis-empower their supporters?

UPDATE (2:30 pm): Also, don't Democratic donors to and supporters of SFC, SF, and DFER realize that when they support and give money to these organizations, they are helping GOP candidates who are part of an anti-woman, anti-immigrant, anti-LGBT, anti-reproductive rights platform. Why would they want to work to elect people with those views?

I am not asking these questions facetiously; I really don't get it. What is it that I am missing? Someone please explain it to me.
