From the newly unearthed audio here:
Speaking to the Jewish Press about the January 25, 2006, election for the second Palestinian Legislative Council (the legislature of the Palestinian National Authority), Clinton weighed in about the result, which was a resounding victory for Hamas (74 seats) over the U.S.-preferred Fatah (45 seats).
“I do not think we should have pushed for an election in the Palestinian territories. I think that was a big mistake,” said Sen. Clinton. “And if we were going to push for an election, then we should have made sure that we did something to determine who was going to win.”
