Teachers used to be an important part of the big blue voter coalition that made the old Progressive Conservative Party an electoral juggernaut from 1971 to 2015.
There was even a former ATA President, Halvar Johnson, who served as a PC MLA under premiers Peter Lougheed and Don Getty and later as a cabinet minister in Premier Ralph Klein’s government. The relationship between teachers and the PC government had its rocky moments, but it was still common for teachers and even ATA officials to attend and participate in debates and votes at PC Party conventions.
