Montrose is a powerfully Republican county. It has not been won by a Democratic Presidential nominee since Lyndon Johnson‘s 1964 landslide - indeed since then, no Democrat has managed forty percent of the county's vote. The county has leaned Republican ever since 1920; although before this, it did tend to vote Democratic between 1896 and 1916 except during the landslide loss of Alton B. Parker in 1904.. How many years since Montrose County started leaning Republican did it vote for Lyndon Johnson?
