If there is an incumbent who actually fights for the conservative cause instead of resting on their laurels and being content with a little pork for their constituents, then vote them back in. But if they are living large on the government teat and doing nothing but protecting their jobs and taking care of special interests then they need to go.
Too many of our politicians lose their fire, they get fat and lazy, they get too chummy with the enemy and the special interests. We have voted the moderates in time and time again, assuring ourselves that they are better than the blazing liberals, only to find out that they’re not.
James Inhofe comes to mind. He has been relentless in his opposition to the enviromentalist whacko crowd and the cynical opportunists like Algore, et.al., who use them to advance their money-making schemes on the backs of taxpayers.
