Today in car crashes that will be politicized:&nbsp;Former Rep. Alan Grayson, who spent two short, memorable years in Congress (though he&amp;#8217;s hoping for a second chance), ran a red light with his Mercedes&nbsp;and hit a city bus Saturday. He was rushing to get to an upscale fundraising event. Two people on the bus got slight injuries; the police found that Grayson was to blame for the accident. As with everything he does, the reaction has been loud and uncompromising:&nbsp;Here&amp;#8217;s a sample of the ways this is getting played so far.
