Collin County is a Republican stronghold in presidential and congressional elections. The last Democrat to win the county was Lyndon Johnson in 1964. The factors caused Collin to swing hard to the Republican Party in the 1960s and 1970s: and the expansion of the Dallas suburbs into Collin County. However, since the mid-2010s, Collin County has been slowly moving towards the Democratic Party, particularly in Plano and Frisco. Factors causing this shift include an influx of younger professionals and families, a more diverse population (with increasing numbers of African-Americans along with recent immigrants and their children), and an aversion to Republican Party politics following the 2016 presidential election.
