I wholeheartedly agree with you but I can also understand why many people who do vote tirelessly do feel frustrated and helpless when stuff like this happen even when they have done their damnedest.
Unfortunately until more non-voters are voting in
every election, there's never enough that any of us can do. We still have to work harder even if we're making the evening and weekend phonecalls and showing up to voter registration drives. We have to make up for a
massive handicap that's been put in place by years of consistent Republican success at the local and state levels. Those elections are arguably far more important than national elections because without them, we don't have the safeguards that keep our elections fair and balanced.
Elections in America
are unfair right now. More Democrats have to vote than Republicans just to keep equilibrium in place. There's no instant solution to it either because of the last 12-24 years of Democrats failing to show up consistently in local elections.
There's a lot more work to be done to make up the difference and the fastest and easiest way for everyone to do it is to get more non-voters engaged, not to downplay the significance of voting or to keep our heads hanging low for too long after every defeat. It's just giving in to the Republicans' voter suppression and voter depression tactics. It's 100% a part of their game plan for us to discourage each other from voting and to keep us pointing the finger at one another instead of helping the less-politically-active have their voices heard.
