Des Moines, Iowa — 135,000. That’s the “magic number” to watch Monday night as Republican caucus-goers gather around the Hawkeye State to choose their presidential nominee, according to data collected and analyzed by numerous GOP campaign officials.

Four years ago, a record-breaking number of Iowans — 121,503 — participated in the Republican caucuses. If turnout exceeds 135,000 this year, GOP insiders agree, it will be an indication that Donald Trump has attracted a significant number of new voters to the caucuses. And if the increase is even more drastic — say, upwards of 150,000, which some Republicans believe is possible — then Trump will likely win.

But if turnout is below 135,000, Iowa will be Ted Cruz’s to lose.
