Never would have thought that Portman would be way more vulnerable than Toomey.
People on the forum overly focus on how the Democratic Party messes up, but this case it's a tale of two statewide Democratic Parties - Ohio recruited their best candidate and a guy who is generally a statewide institution, while Pennsylvania is actively trying to implode their main candidate in Sestak. There is the difference, which is noticeably shocking considering both Toomey and Portman are popular in their states.
Well, with Sestak there are still a lot of top democrats who hold a grudge on him for defeating specter 6 years ago, as Specter would have defeated Toomey in a general election. But the fact is that unless Ed Rendell runs, and all signs are that he won't, Sestak is the best democrats have here.
