I've often heard in the past that if you didn't bother to vote, then you have no right to complain. And I generally agree with that statement.

Too bad John McCain doesn't. Here he complains about "partisanship" in the Medicare bill that he didn't bother to show up to vote on. In fact, McCain has made a habit of missing big votes in the Senate. He missed voting on the FISA bill, the new G.I. Bill (which he took credit for after opposing it from the start), and he's missed 10 of the last 14 votes on the Iraq War. McCain even criticized Barack Obama for missing the vote on the Kyl-Lieberman amendments on Iran, when he himself missed that very same vote.

To be fair, Obama has missed 45 percent of the votes this session. But McCain has missed 61 percent. And while Obama shows up for important votes, McCain doesn't, preferring to complain and attack from afar.

If he's not going to vote on these issues, maybe he should do what Bob Dole did in 1996 and resign from the Senate, since it's obviously not a priority for him. The people of Arizona deserve to have full representation in the Senate.

And Sen. McCain, if you aren't going to bother to show up for these votes, you have no right to complain.
