It's been fun to watch Republican Party leaders on Capitol Hill snarl at one another the last few weeks. House Republicans are livid at their Senate colleagues, especially Majority Leader Bill Frist (R-Tenn.) and Finance Committee Chairman Chuck Grassley (R-Iowa), for approving a $350 billion tax cut. "It's time that Mr. Frist gets his chamber in order," one House aide told The Hill. Senate Republicans, meanwhile, feel their House counterparts, who passed a $550 billion tax cut, don't understand how hard it is to govern in a chamber where one senator can hold up debate and where their party has a mere two-vote majority.

One of the more useless means of measuring support for the presidential candidates is now underway: the race among candidates to win endorsements from members of Congress. It carries little if any weight with voters -- most of whom probably don't even know it's happening -- and doesn't mean much for the candidates or the lawmakers who endorse them. Still, it's a way to feed the press beast, which is always looking for new information about the men (and woman) who want to win the nation's highest office.
