Does DC have an open or closed primary? If closed, Republicans may not support Nikki.
DC is a closed primary.
Only registered Republicans can vote there.
Registered Republicans are only 5% of total DC voters—so we are talking small numbers.
In 2020 only 1500 (that is not a typo, 1500) people voted in the Republican Presidential primary. It was uncontested and all delegates were awarded to President Trump.
