Politics
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 since1920; although before this, it did tend to vote Democratic between 1896 and 1916 except during the landslide loss of Alton B. Parker in 1904.
In other offices, Montrose also is strongly Republican. The last Democratic Senatorial candidate it backed was Ben “Nighthorse” Campbell, who was later to shift to the Republican Party, in the 1992 election, and since then no Democratic Senatorial candidate has passed forty percent either. Montrose County did back Constitution Party nominee Tom Tancredo in the 2010 gubernatorial election, and Bill Ritter did win 46 percent in 2006, but Roy Romer in 1990 remains the last Democratic candidate for governor to win Montrose County.
