Bullock is nowehere near as "conservative" or "moderate" as people here seem to believe he is, so his crossover appeal is extremely exaggerated. Another thing to keep in mind that Bullock running for president could very well result in him losing the nomination (extremely likely) and Steve Daines winning reelection to the Senate, so it would be a lose-lose situation for Democrats. Like I said before, Daines could lose to some other Democrat as well, but Bullock would be their best bet.
Yeah, but Bullock doesn't need to be conservative OR moderate to reach out to culturally moderate-to-conservative Obama-Trump voters.
