No, that’s not how to win. One must not only win, one must be seen to have won, and to have taken a credible fight to the enemy’s home territory is part and parcel of being seen to have won. It’s a matter of morale which, like goodwill or any other intangible, is priceless, and by that I do not mean without value.
You have a better change of winning over 400 seats before you have the most remote chance of securing a district with less than a 10% Republican presence. Gnat on a windshield. And with all due respect, that’s not how to win. You take back the seats that they have no business occupying. Render the opposition impotent. There’s a difference between heroism and pure insanity.
