My wife and I are eagerly awaiting #9.
I'm not sure that annoying Liberals is a good thing. Sure, it is satisfying. But my opinion is that they already use a lot more energy than Conservatives to further their ends. "Encouraging" them to go in greater numbers to the ballot box is self-defeating. In the recent Virginia House and Senate elections, where the Governor hoped to flip them both to Republican control, he lost control of both due to highly energized Abortion Rights advertising by the Democrats. Ultimately, it is about who can get their "base" the most fired up to vote. Especially in the "down ballot" races where a lot of the power over our daily lives lies, we in the Grass Roots groups have lost a lot because a higher ticket race drew voters. with the sharp divide between camps, just a few votes can swing an election. I view many liberals as zombies. They operate with almost no common sense. An for the few that do display any sense of reality, their common sense is wiped out by the "orange man bad"type of propaganda. The rats would follow one another off the cliff rather act in their own best interests. We don't need to energize that any more.
