So lets discuss which Democratic Representatives need to be primaried in 2020

Ocasio Cortez(self explanatory)
Ilhan Omar (see above)
Rashida Tlaib (see Ocasio Cortez)
Maxine Waters (see Ocasio Cortez)
Collin Peterson(to make Dems lose MN-07)
Jeff Van Drew( to make Dems lose NJ-02)
Pramila Jayapal (cosponsoring an unaffordable healthcare system)

So, Democratic representatives should be primaried because...they're in line with their party's goals?

Not only. I would oppose primarying Peterson, Van Drew, or Jayapal, as they've done nothing to warrant it. Waters, however, is corrupt and is one of the most ignorant members of the House. Tlaib and Omar are anti-Semites, and Ocasio-Cortez has done much to warrant a primary challenge.

Jayapal was one of the first supporters of Medicare for All, Seattle deserves a representative who does not want to spend exorbitant sums of money on healthcare and can find cheaper, effective solutions

Seattle deserves a representative that, well, represents us. M4A is hugely popular here.

ITT: People who are not Democrats and clearly don't have much contact with Democrats claiming to know more than actual Democrats about what Democrats want and what they should do.

I’m sure the “reasonable moderates” here think that very conservative Republicans in dark red districts should be primaried by moderates as well
