This is showing something that I’ve been saying for nearly 20 years. If a Republican wants to win the election, they need to win the vote outside the margin of error (typically 2-3%). If the election is any closer, then the Democrat vote ginning machine is usually able to steal the election.
You’re seeing this in play now, before the November elections. Democrats aren’t trying to win in a lot of these races. They’re just trying to get close enough for their election stealing machine to go to work.
