I feel like so many endorsements of Hillary start off with “I’m not a big fan of Hillary, but…”
Not sure that’s a super helpful endorsement, and I also feel like it’s a kneejerk meme that reflects the GOP’s successful branding of her as an unlikeable candidate. A lot of people who express the sentiment rarely articulate why they’re not a “big fan” of her.
If you truly don’t like her but still want to endorse her because she’s better than the alternative, then fine. But I also think this is a good time to examine why you don’t like her and whether you actually diverge from her in your core beliefs. If there isn’t that much of an ideological difference, maybe consider the possibility that you could, in fact, like her?
