MADISON, Wis. -- The tedious task of recounting Wisconsin's nearly 3 million votes for president began Thursday with scores of hastily hired temporary workers flipping through stacks of ballots as observers watched their every move.

The action in Wisconsin soon could be duplicated in Michigan and Pennsylvania, where Green Party presidential candidate Jill Stein was pushing for recounts.

Donald Trump narrowly beat Hillary Clinton in all three states, but recounts were not expected to flip nearly enough votes to change the outcome in any of the states.

The Wisconsin recount marked the first time in 16 years there was a candidate-driven recount of a presidential race. But it does not carry the same drama as the Florida presidential recount of 2000, when the outcome of the election between Al Gore and George W. Bush hung in the balance.

"This is certainly not Bush v. Gore," said Wisconsin's chief elections administrator, Mike Haas.

Even so, the campaigns for Trump, Clinton and Stein all had observers spread throughout the state to watch the process. The recount will have to move quickly. The federal deadline to certify the vote to avoid having the fate of Wisconsin's 10 electoral votes decided by Congress is Dec. 13.

Even if that were to happen, the votes would almost certainly go to Trump, since Republicans control both chambers of Congress.

Most counties will recount the ballots manually, although Stein lost a court challenge this week to force hand recounts everywhere.

The state's largest county, Milwaukee, was recounting the ballots by feeding them through the same machines that counted them on election night. In Dane County, where Clinton won 71 percent of the vote, the ballots were being counted by hand.

Workers in Dane County are being paid $20 an hour and will work two shifts over about 12 hours a day to get the recount done by the deadline, County Clerk Scott McDonell said. He didn't expect much change in the results.

"I think we will be very close to what was reported on election night," McDonell said Thursday.

Clinton lost to Trump by about 22,000 votes in Wisconsin, or less than a percentage point.

Stein has argued, without evidence, that irregularities in the votes in all three states suggest there could have been tampering with the vote, perhaps through a well-coordinated, highly complex cyberattack.

"Verifying the vote through this recount is the only way to confirm that every vote has been counted securely and accurately and is not compromised by machine or human error or by tampering or hacking," Stein said in a statement Thursday.

Stein's critics, including the Wisconsin Republican Party, contend she is a little-known candidate who is trying to raise her profile while raising millions of dollars.

Stein has taken in nearly $7 million for the recounts, which is about twice as much as her longshot presidential campaign took in.
