Vermont Voting Pattern

Before the Democrats...

From Wiki:

"...Republicans dominated Vermont politics from the party's founding in 1854 until the mid-1970s. From 1856 to 1988, Vermont voted Republican in every presidential election with only one exception in 1964. Vermont consecutively had Republican governors for over a century until Democrat Phillip Hoff was elected in 1962. Prior to the 1960s, rural interests dominated the legislature. As a result, cities, particularly the older sections of Burlington and Winooski, were neglected and fell into decay.^{[citation needed]} People began to move out to newer suburbs.

In the early 1960s many progressive Vermont Republicans and newcomers to the state helped bolster the state's small Democratic Party. Until 1992, Vermont had supported a Democrat for president only once since the party's founding—in Lyndon B. Johnson's 1964 landslide victory against Barry Goldwater.."
