I've argued this point many times before. You send a message by voting for the opposition candidate.
Heh, well, I don't see that as sending a message either. Nobody cares
why you voted a certain way, and ultimately, there isn't even any way for them to know why. All they see are the vote totals. For all they know, your vote was more a reflection of support for the leftist policies of the person elected, not a protest vote against the other guy because he wasn't conservative enough. I don't think a conservative "messages" actually gets through except to the extent you actually elect someone with the point of view your support. That message gets through simply because of the fact that the guy got elected. But every other "message" gets lost in the noise.
In the Senatorial elections of 2014, I urged Kentucky and Mississippi conservatives to vote for the Democrat. By electing a Democrat in strong Republican states, you would have sent a message that the behavior of those Republican candidates who deliberately attacked their constituency (Mitch McConnell and Thad Cochran) will not be tolerated.
I think the
only message that gets sent is that you preferred the Democrat to the Republican. That's it. The "why" is completely lost, and there is no way to distinguish your vote from the vote of a lefty who just looooved that Democrat. Someone could just as easily interpret your vote as the state being further to the left than they thought. And ultimately, the next time that election rolls around, all they're going to care about is the votes they get in the primary, not the speculation as to why a certain candidate lost last time.
Instead, there were all these whiners saying " There is no way I can vote for a Democrat", and so they just sent the exact wrong message. They sent the message that "of course we will tolerate underhanded and vile tactics used against real conservative opponents of establishment candidates. "
Again, I just don't think that "message" actually comes through the way you intended. It is just a vote, with no codicil or explanatory statement. It actually carries the potential for sending the opposite message as well, because the next time, they may think the only way to win is to move closer to the Democrat positions, because that's what won the last time.
