It's been a while but didn't her parent's political connections get her that internship? And wasn't her mother (and aunt, come to think about it) bragging at all the DC parties that Monica was doing the president?
I seem to recall that at some point the Starr Report quoted Monica as saying that after she and Clinton had at least one of their early "sessions," she saw him again and had to remind him of her name. She was in there with him, doing that, and he doesn't even know her name? And yet they both continue with future episodes. I think just about says it all about both of them.
