As un-democratic the electoral college is, the US parties do a much better job in picking candidates in a democratic manor. Especially when compared to Germany, our parties run their party leaders as top candidates for chancellor. Party heads are elected by party members, but in practical terms any results under 85% plus percent is already seen as a lack in confidence.

So yeah, who ever wins party primaries is the candidate the parties base wants. Obviously, distorted by money, but still.
