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.. What happend first: Lyndon Johnson becoming the Democratic Presidential nominee or Alton B. Parker's landslide loss?
