ST. PAUL, Minn. – Polls suggest Minnesota may become one of a half-dozen or so battleground states for the presidency in November. An early April poll by St. Paul television station KTSP showed that Biden leading Trump 44% to 42%, within the margin of error. Some 11% said in the snapshot that they would vote for someone else. And 4% were undecided. A MinnPost poll last fall showed a similar neck-to-neck statistical breakdown. Even so, most smart money favors Biden. Historians note that Minnesota has not voted for a Republican for president since Richard Nixon. Also, the Biden campaign warchest has been raising more in the state than Trump.
