3) The Appropriators: If there's one defining difference that separates Republicans from Democrats, it's spending. Republicans want less of it, Democrats want more -- well, at least that's how it should be. Yet, there are big government Republicans. There are Republicans who love earmarks. There are Republicans who think it's fine to fritter taxpayer money away, but they just want to waste a little less than the Democrats. These people are not just killing the Republican brand; they're helping to ruin the country.
4) The Bubbleheads: One of the idiosyncrasies of D.C. Republicans is that many of them are smart people, they're well informed, they have inside info, and they consider themselves to be conservative -- yet they have no idea how out of touch they are with the base and the rest of the country. This is how you end up with Republicans supporting Bridges to Nowhere, increased National Endowment of the Arts funding, or pushing comprehensive immigration reform and Harriet Miers. The average talk radio listener or blog reader has a better read on politics in some areas than senators and congressmen because they're not mired in that D.C. bubble with aides, consultants, pollsters, and lobbyists all pushing the same monolithic way of thinking. If you're a Republican in D.C. who doesn't get that, you're part of the problem, not part of the solution.
5) The Compromise Fetishists: There's nothing wrong with compromise per se. Republicans should be willing to compromise with Democrats -- if it's on a bill that will make the country significantly better overall. How many bills are there fitting that description that have been passed in the last decade or so? Certainly no more than a handful -- and none have been passed during the Obama Administration. That's because "compromise" in D.C. usually starts with the idea that Democrats get 90% of what they want and then Republicans negotiate to see how badly they're going to lose. Yet, we hear some Republicans lauding compromise like it's a worthwhile goal in and of itself. A compromise on a bad bill isn't a win. Did Republicans make a mistake by refusing to work with the Democrats on the stimulus or Obamacare? Should they have worked with Obama to raise taxes, pass comprehensive immigration reform, or to do another stimulus? Of course not! Half of stupid is still pretty stupid, stupid.
