Now Minnesota is Moving Up to Feb. 5th

I guess Minnesota will move up their primary to February 5th.

Previously, though Minnesota Republicans were planning to caucus on Feb. 5, the Democrats had been set to meet on March 4. The move adds Minnesota to the nearly 20 states that now plan to choose their presidential nominees on the first Tuesday in February.

20 states voting on 1 day? Do these states actually think candidates will be able to campaign in those states?
