Jonah Goldberg thinks not. Doug Mataconis sees them as something of an overreaction:

We elect officials to serve specific and set terms of office for a reason, among those reasons are the idea that it takes a certain amount of time for anyone, whether they are a State Legislator, Governor, Member of Congress, or President, to get settled into their role and begin enacting the agenda that they were elected to implement. Obviously, the people who voted against those officials aren’t going to be happy with the policies that they implement, and indeed it is partly the job of the opposition party to stem the power of the majority run roughshod over the will of the minority, though. However, there comes a time when one must recognize that elections mean things and that one has to accept the outcome of an election while preparing for the next one.
