In Presidential Elections since 1980 that seems to be the case - and with Democratic voters.
Bill Clinton and Barack Obama - rock stars
Hillary, Gore, Carter, Mondale, Kerry, Dukakis, doubtless lovely people, many, most or all of whom would have made perfectly satisfactory presidents, but IMO they lacked the wow factor that would have turned out the vote.
OTOH, Republicans seem to like personable dopes.
Reagan, Dubya, Trump all managed to convince Republican voters that they were the kind of person they would like to spend time with - George HW was an outlier. OTOH Dole, HW (second time), McCain and Romney all came across as smart but somewhat unapproachable.
I think this is a case of "over-fitting" the data. Al Gore and Hillary Clinton received more votes than their Republican rivals so it can't simply be a case of voters being turned off by "non-rock stars". You also have to factor in other variables such as the electoral college, or party strategy.
Besides, is Trump "personable"?
