"The immediate impact is that the GOP became that much less likely to take over the Senate in November. A clear Republican win in Delaware became a likely Republican loss. But though that’s getting all the headlines, it slightly misses the point: The long-term impact of these primaries is not going to be on the incumbents who have been defeated. It’ll be on the incumbents who survived.
It was hard for incumbent Republicans to see Sens. Bob Bennett and Lisa Murkowski unexpectedly toppled in their primaries. But Alaska and Utah are conservative, quirky states. They were likely targets for an angry conservative electorate. The same cannot be said for Delaware, a moderate state that often goes blue. Rep. Mike Castle’s defeat was proof that no heterodox Republican is safe from a primary defeat — it doesn’t matter how popular you’ve been, or how clearly purple your electorate was. You’re not safe. You’re never safe.
Politicians are, by nature, a fearful species. But their nightmares became a lot more specific last night. The Tea Party, for all its unexpected successes, cannot topple every incumbent Republican in the country. But by toppling the right ones, it can make every incumbent Republican vote and speak and act with the Tea Party in mind. So though the Tea Party isn’t likely to send all that many of its own Republicans to Washington, the likely outcome of last night’s primaries is that the Tea Party takes over the Republicans who are already in Washington, and don’t want to be sent home.
