The recount in Wisconsin, and the coming ones in Michigan and Pennsylvania will not change the outcomes in any of the states.  No recount ever changes thousands of votes.  I do not think that is the purpose.

The recounts, if done by hand, which can be demanded, may take longer than the last day for completing the official counts in a state and directing Electoral College voters.  If all 3 states miss the deadline, Trump is at 260, Hillary at 232.  No one hits 270.  

Then this goes to Congress, where the House voting 1 vote per state elects Trump, and Senate selects Pence. This would be first time Pthis happened since 1824, but in that case, John Quincy Adams won in the House, though he had fewer electoral college votes than Andrew Jackson.  

If this goes to the US House and Senate, and the result is the same as result from the Electoral College without the recounts, why do it?  The answer is to make Trump seem even more illegitimate, that he did not win the popular vote  (he lost by over 2.1 million), he did not win the Electoral College (did not reach 270), and was elected by being inserted into the presidency by members of his own party in Congress.
