(This caricature of Kellyanne Conway is by DonkeyHotey.)Kellyanne Conway is not the worst person or the most dangerous person in the Trump administration. She doesn't have enough power to hold either of those titles (and Bannon has them locked down anyway). But she does have to be the biggest joke in the administration.
This woman is not afraid to look stupid, and she does it often. She regularly tells the most outrageous and obvious lies, and she does it with a straight face. If the Trump administration does something dumb (which seems like it will be a regular thing), you can count on Kellyanne Conway to worm her way on as many news shows as possible to lie about how that dumb thing was actually a brilliant move by Trump. She does this in an effort to make herself look good to Trump.
But the media has finally figured her out. Some, like Mika Brzezinski of Morning Joe on MSNBC, has declared that Conway will no longer appear on that show. She says, “She’s not credible anymore.”
And she's not the only journalist to reach that conclusion. An anchor on a different network (who wanted to remain anonymous) said Conway is no longer invited to appear because “she constantly obfuscates and misrepresents the truth.”
Other journalists, like Jake Tapper of CNN and Matt Later of NBC, seem to relish interviewing Conway these days -- because they know she will lie, and they can attack those lies (making themselves look good in the process).
I think Conway is just trying to be a "good soldier" for the administration by showing her loyalty to Trump. But the constant barrage of lies she tells to do that has just destroyed her credibility, and it's made her little more than a joke.
