Mr. Obama, during his private pep talk to Democrats, recognized Mr. Owens’s election and then posed a question to the other lawmakers. According to Representative Earl Blumenauer of Oregon, who supports the health care bill, the president asked, “Does anybody think that the teabag, anti-government people are going to support them if they bring down health care? All it will do is confuse and dispirit” Democratic voters “and it will encourage the extremists.”
