Some Colorado caucus meetings were so crowded that they moved outside Tuesday.
At Hill Middle School in Denver, Denver7 reporter Marshall Zelinger found long lines outside and inside, but said they managed to get everyone inside.
However, at East High School, there wasn't enough room for everyone.
At a location in Fort Collins, caucus goers were also moved outside.
Denver7 viewer Ruth Jarles emailed us and said, "Three precincts having to meet outside in Edgewater!"
Another viewer, David, said, "Incredible turnout at Hamilton Middle School. Line is almost 10 blocks right now."

Denver7 reporter Marc Stewart found extremely long lines at North High School.
At Preston Middle School in Fort Collins, Logan King said the caucus was "packed."
Marti Hopper said there were so many people at her caucus location in Boulder, that they had to wait 90 minutes for everyone to get checked in.
