You had a choice between Mitt Romney and Barack Obama. I'll take your word that Romney supports abortion and gay agenda. So does Obama.
So what do you do? You attack Romney. Obama wins, and we end up with a big mess in everything that Obama has touched.
Democrats win by advancing the ball a few yards at a time. Eventually they get where they are going . Single issue voters want either everything or nothing, right away. And they discourage others by posting divisive messages against other that mostly agree with them.
You keep using the liberal code words “single issue”, which “single issue” is it that you want conservatives to drop?
