The Dems are so deluded is almost beyond belief, except they are Dems and delusion is their middle name. They keep catering to the left wing of their party and more people decide they are not Dems and become independents, more independents decide they are GOP or favor the GOP, and the ranks of the GOP are increasing. They are actually driving voters away from them in droves. Their behavior is insane, if they actually believe it will help their election prospects.
I’m not sure that behavior is irrational. If they can attach people to the teats of government faster than they drive people into opposition to their plans at the ballot box, they win.
They will acquire millions of new voters as soon as they pass immigration reform. In addition they are creating millions of new government jobs. Those government workers will certainly vote to keep them in power.
