In my opinion this is debatable. Obama courted Republicans in 2008 and in a big way. He made an ally out of Bill O'Reilly and pissed off Sean Hannity. He got on James Dobson's bad side, which sparked a counter-revolution from other white evangelical pastors joining together to say, "#JamesDobsonDoesn'tSpeakForMe". Obama received endorsements from Colin Powell, and others. even McCain, after the election was over, said some of Obama's cabinet appointments, he would have made himself.

I think Joe Biden also courted Republicans who were disaffected by Trump.

Hillary, was uniquely loathed by the entire conservative 1/3 of the country. But Hillary did court Business, which could have been a boon or a curse, you decide that one.
