"Crowley can't campaign on a moratorium because that's a legislative issue" is a flimsy anti-moratorium argument
It's ridiculous to suddenly pretend that candidates for the executive branch in any election in the country only ever campaign on powers entirely within the executive. One of the biggest things the governor does is set the docket for the session in his or her budget. His or her election serves as a referendum on whether those issues are popular, which then informs his or her negotiations within the legislature.
If you believe that Crowley can't advocate for a moratorium because it's a legislative issue, then you should be consistent and believe he shouldn't campaign on school funding reform, cannabis legalization, housing finance, or anything beyond "here's who I'll appoint to my cabinet and here are some executive orders I'll sign." Which is preposterous!
It's fine to say "I don't think Crowley should advocate for a moratorium" if you think a moratorium is a bad idea. But to suddenly argue that it's now out of bounds for a gubernatorial election is, well, cope, and now that Crowley is the nominee it's popping up everywhere.
