This Cruz dirty tricks department FUD has already been posted a dozen times on FR in the last hours.
The only reported difficulties were a shortage of ballots due to the exceedingly high turnout:

There are no ‘poll workers’ at caucuses. These are informal events where you and your neighbors get together and try to convince each other whom you and they should vote for. Voting is then conducted on little paper slips passed around the tables and then collected and counted.
The guy in the pic isn’t collecting votes; he’s registering people who want to attend the caucus. Everyone involved are volunteers and wearing candidate gear is expected because the purpose of these meetings is to promote your candidate.
It works exactly like this in Colorado.
All of these claims of impropriety are complete BS FUD being spread by the losers in an attempt to prey on peoples ignorance as to what a caucus is and how they function to try to excuse their candidate’s MISERABLE performance.
IOW, you’re trying to deflect everyone from your candidate’s corruption.
