I have yet to meet anyone - though I know they exist - who honestly thinks that much is going to change if the Democrats win the House.
The general sense I get is that those who want the Republicans out feel things will deteriorate less slowly. Given the scale and pace that things have deteriorated over the past six years maybe to expect more is too ambitious.
[ . . . ] this is one Republican who has never voted for a Democrat in his life who will do so this year for the first time. I will cast my inaugural Democratic vote in the sincere belief that continued Republican control of both houses of Congress and the White House is not in the national interest and is harmful to the conservative agenda I have worked all my life to implement.
