The answer to this should be a self-evident "yes," as activists like myself get involved because of the emotional or intellectual pull of specific causes or issues. Many average citiziens do not even begin to pay attention to political campaigns until after Labor Day, whereas activists are engaged mostly year-round. "Average voter" is something of a misnomer in political science circles, since there really is no such creature, but there is such a thing as "registered voters" and "likely voters." As you might expect, "likely voters" tend to be polarized a bit more than the more-general "registered voters."
I hope this answer helps. Please let me know if you need any more help with this or any question involving government and politics.
