Eddie Bernice Johnson Schools "Taliban Pete" During Dallas Forum

My area's Tom DeLay gerrymandering-imposed congressman, "Taliban Pete" Sessions (R-TX-32) and the congressperson who represented our area before DeLay railroaded his gerrymandering scheme, Eddie Bernice Johnson (D-TX-30) co-hosted a healthcare forum today in Dallas.
Here's the link to the meeting that's on the web site of our area's CBS affiliate.
I just saw a clip from the meeting that was broadcast during the 4 p.m. news, and "Taliban Pete" looked stunned when Johnson disputed him on Sessions' oft-propagated lie that the president's healthcare proposal amounted to "socialized medicine."
Is Sessions also against Medicare? Is he also against the VA?
If he's so much against socialized medicine, why doesn't he oppose the above two programs? (It's the same question that Lawrence O'Donnell posed to another Texas Republican congressman Friday, and the congressman couldn't answer the question).
