This "logic" doesn't track at all. Enfranchising women may have benefited the party, does that mean we shouldn't have given women the vote and doing so hurt democracy? Of course not.

Just because something benefits a singular party doesn't make it antidemocratic. Expanding the franchise is more democratic, not less. A party being rewarded electorally for doing something good is the system working, not failing.

There are reasonable arguments to be made (in my opinion) that 16 is too young but you aren't making that argument, the one you are making is completely invalid.
