What cash crop was responsible for saving the colony of jamestown

Tobacco
most people smoked tobacco as a result people needed to trade or buy which made Jamestown prosperous

I believe that the best answer for this question would be the third answer. President Lyndon B. Johnson won the 1964 election with 486 electoral votes, versus his opponent's, Barry Goldwater, 52 electoral votes. Johnson also garnered 61.1% of the popular vote. It was the highest-won election by a candidate since 1820. Hope this helps.
