You have to make it beneficial to them. "Yeah this thing is a lot cheaper and more reliable than my old car and I hate having to go to gas stations with all those shady people" goes a lot further than, "We need to adjust our habits to curb a runaway greenhouse effect and the best we can hope for is only 2.5C warming by 2100." One makes them consider electric; the other makes them avoid (and hate) you.

Either that, or just convince them not to vote. "Yeah the election was rigged, not even worth it to go vote anymore."
