Strongest candidate wins the primary...if you can’t win people in primary how will you win general?...for presidential elections partisans need motivation it is not just some governor election where people don’t really care and you can walts in like Desantis.
Are you saying Oz was the strongest candidate? Walker was the strongest candidate? Doug Mastriano? Tudor Dixon?
Many races are lost because lousy candidates win primaries over candidates that would've fared better in the general election.
