Liz Benjamin reports that Republicans are trying to tie Charlie Rangel [NY-15] to Eric Massa and other candidates for whom he's raised funds. Rangel has some rent-controlled apartments in New York for which he's paying less than the going market rate. You can read Rangel's defense here. I'm not an expert in rent control, but I thought that the whole point of the law was to allow people to keep renting at below-market rates.
Rochesterturning has a post about Massa's quick response when it appeared that some campaign donations were accidentally channeled to his campaign.
