As I have been saying since before the 1016 election, Liberals have been campaigning on the wrong issues.
Americans no longer feel great. They are full of angst and fear. The people of the world are advancing largely to American efforts with the result that jobs have gone overseas. Americans are too soft and too well fed to compete and the political system does not serve their interests. And it's our liberal non national all inclusive liberal attitudes that have created this situation.
All that Republicans need to do to win is point to liberals as the source of the problem. They care about everybody and anybody but you. And all you have to do to stimulate this rage against the named powers that be, liberal democratic institutions, is to make sure that any adjustments to liberal policies never get a chance to work. The way to power is to blame the powers that be for your misery and claim to be an outsider as you paralyze the system.
In a system that fails to work the promise of fixes fall on deaf ears.
What democrats need to do is to identify Republicans as the real cause of the problem which is hard because it takes money to run for election and it's the one percent who has all the cash and they do not want the system made equitable. And instead of appealing to the voters who feel the most threatened they appeal to those who are the most blamed for it. Those are not the people deceived into voting for the very state of paralysis that generates all their hate. They are the ones that need help waking up, the 'conservatards' that liberals write off and make sure are sufficiently insulted to turn away form any hope of the light.
