I figured every bit of local ad time time was soldout. So they were forced to buy national time.
Only the candidate’s campaigns have guarantees of low ad prices - PACs and unaffiliated groups don’t. Depending on the conditions, a national ad buy can actually be cheaper for these groups.
Republicans only list their accomplishments to Republican audiences like Trump rallies. They preach to the choir. This is why it is The Stupid Party. No common sense.
