The national media have gone crazy with misrepresenting the recount efforts. Both Stein and Johnson underperformed their polling numbers. Stein and many Greens want all the votes counted and verified. In Wisconsin, there were votes for Stein that were credited to Clinton. A lot of tampering with ballot boxes has been found in Michigan.
La Roque also requested a recount in WI, I think, and in NV. A different group requested one in FL. Candidates are not allowed to request recounts in FL. In WI and MI, candidates are the only ones who are allowed to request recounts. Laws vary from state to state.
