joining me to discuss what challenges may be ahead are democratic strategist chris lehane and scott detrowsacramento bureau chief for kqed joining us from los angeles, where he's covering the convention. and scott, let me start with you. what impact are these scandals, including the investigation of senator ronald caldron of southern california, what impact are they having on democrats, if any? >> i think democrats are definitely concerned about this, and you know that because state senate leaders announced a big ethics reform package this week that would half the amount of gifts lawmakers can receive and lead to more disclosure, and this is clearly a response to the fact that ron caldron is facing massive criminal charges on ethics issues. and rob wright, another senate democrat, has taken a leave of absence from the senate after being convicted of not living in his district. democrats pushed back on this, saying these are isolated incidents and you can't tie them to party leads, but the fact is, caldron especially has made a point to try to drag other democrats into the scandal with him.
