Politics is a nasty, disgusting, and vile world. I expect people to say all kinds of things about me. After all, I have real solutions that many people support. This makes me a threat on an ideological level. If I acknowledge and respond to each and every stone thrown my way, I will have less time to talk about the solutions to our problems. I refuse to allow my opponents to distract me from the positive, solutions-based policies I am proposing.
Plus, I am focused on solving the problems that affect YOU. While my opponents may want to focus on fairy tales to distract you and me, I will not be distracted from fixing what's broken in our nation and our district. While politicians engage in mudslinging, a genuine candidate is simply too busy with improving the lives of his or her constituents to engage in, or respond to, that type of juvenile behavior.
Therefore, I will not respond to such attacks, regardless of whether the attacks are true or false. In my experience as a citizen and voter, around 90% of allegations are false smears to meant to derail a candidate who is succeeding. A wise person takes it all with a grain of salt and a generous helping of skepticism. My parents used to say, "Believe none of what you hear and only 1/2 of what you see." And they are very wise.
