No. Challengers cannot challenge a voter’s registration simply on a whim. Challengers must have personal knowledge that the voter is not eligible to vote and must sign an oath attesting to the validity of their claim.  See the fact sheet Challenges and Vouching Must be Based upon Personal Knowledge! for more information.

It depends. If you are eligible to vote but your home is currently in the foreclosure process you can still vote. Voters must vote in the precinct in which they reside. If you moved out of your home and do not intend to return, you need to register to vote by providing the address of your new residence.  See Voting Rights for Minnesotans Facing Home Foreclosure for more information.
