Many commentators indicate that Meade would be able to have cross-party appeal which makes him a good candidate for PRI to disassociated itself from the scandals of the current PRI administration. On the other hand he seems to do worse than Chong in various matchup polls. That could change now that Meade is running.
I don't understand how Chong is possibly doing better than Meade in these match ups. Everything in Chong's career since he's went into the administration has been a failure. I have to assume it's just a name recognition thing unless anyone else knows why Chong does better.
