The banner headline on the Drudge Report this afternoon reads, "McCain Defends the Plumber" after McCain accused the media and Barack Obama's campaign of inappropriately scutinizing Wurzelbacher. McCain is right that Americans should be able to ask tough questions of candidates without reporters digging up their background info, Carol Platt Liebau writes at Hot Air's Ed Morrissey, meanwhile, asks why Obama has not called on the media to leave Wurzelbacher alone, given that his campaign has criticized Alaska Gov. Sarah Palin (R) for not denouncing agitated GOP supporters at her rallies.

The Tribune may be Obama's hometown paper, but Obama is the first Democrat it has endorsed in its 161-year history, SusanG notes at Daily Kos after its editorial board backed the Illinois senator for president today. The endorsement is particularly significant because the paper's editorial board is conservative--an alignment the Tribune editors admit in their endorsement piece--writes AMERICAblog's John Aravosis.

Sen. Ted Stevens (R-Alaska), meanwhile, catches heat from one blogger for testimony he gave today at his corruption trial. Stevens basically deflected blame to his wife for the home renovation project, allegedly paid for in part by friends, that has landed him in court, TChris alleges at TalkLeft. Stevens said the renovation was essentially his wife's project, and the blogger claims Stevens is using his busy life as a senator as his main defense.
