I have that page (Google News searching 'tax proposal') and the rest of the content is changing, the picture associated with that group of stories, other links within, yet that lead stays the same. Whether it's indicative of a wholesale endorsement of Obama by Google or just an Obamaphile who found him or herself in a position to pick which articles Google puts on their 'news page' is unknown.
I have screenshots saved from the past hour and everything else changes on the page. Pity Google is getting out of the innovation business and into the political arena.
