Everybody Loves Raymond, 9 p.m., Channels 12, 7.

This season's first three episodes have offered Raymond at its funniest. Last week's was brilliant with Ray prolonging a feud between his mother and his wife, Debra.

Tonight brings a fresh crisis: Ray must relay the news that the PTA doesn't like the way Debra dresses.

Diary of a Political Tourist, 8 p.m. HBO.

Alexandra Pelosi's first documentary, Journeys With George, had charm, but it was fairly flat and one-note. This new film, by comparison, mixes humor with a strong portrait of the primary process.

We see Howard Dean chanting the same phrase over and over. We see the singing Bob Graham clan, which Pelosi calls Partridge Family politics.

It's interesting and a bit sad. As Pelosi points out, the only men who made it to the finish (John Kerry and John Edwards) were the ones who stayed on plan and on message without detour.
