The extreme form would be to ensure that every person who favors your position gets a vote cast and counted, without changing the votes of others.

It's the difference between persuasion and "get out the vote". Persuading voters to your point of view is more honorable, but "get out the vote" is often more cost effective.

Dead people voting is manipulation. Just because more votes are cast doesn't mean they are legitimate.

However, since the post to which you're replying specified more people voting, not more votes, your vacuous statement is not on point. Stop fear mongering and being a pointless pedant.
