Yes and no.
For the statewide haul, you have to be at 20% if the first place candidate finishes under 50% to get delegates.
However, that does not stop you from getting delegates from a Congressional District.
However, to get those delegates, you must finish with at least 20% of the vote in order to get a delegate so long as the first place finisher is under 50% in that district.
Confusing enough yet?
Yes but you explained it well. Thank you!
