Way more than 4, DJ? Last Republican to win it? Ike?
Well before that. Not since 1928 has MN-8 voted GOP for President. It kept its voting habits for Republican William Pittenger (elected on and off from 1928 to 1944), but almost every county in the 8th from 1932 onwards voted Democrat. I didn’t add up the numbers for Ike, but given that Stevensone got over 60% in St. Louis County (Duluth) and over 50% in all but rural Cook County in the NE corner, he probably only got in the low 40s overall. Nixon got as close as 55-45% in 1972 mostly due to the southernmost counties (after 1962 redistricting). And lastly, Willard got within 5.5% of Zero,(46.2%), besting Nixon’s 1972 performance in 2012.
