Okay, there are a fair number of conservatives in this sampling, but a stroll around the web seems to be pretty universial. Biden's attempt to marginalize Ryan with that stupid smirk backfired. The RNC compiled a sampling:
@ErinBurnett: #Focusgroup scoring Biden negative on #libya. #cnndebates
@piersmorgan: Joe, seriously, STOP SMIRKING. This is serious stuff. Be Vice-Presidential. #PMTdebate
@EricWeisbrod Ryan scoring high among women for saying we shouldn't apologize for our values. #cnndebate pic.twitter.com/UoCD4YWu
@AmyeWalter: Seriously, Joe Biden, the laughing/smirking is not working for you. Very curious to hear what voters at home think of it. #debates
@ChuckTodd: Biden laughing a lot... the smirks; all on the split screen. Wonder how it plays with some; Dem base may like it; GOP base hate it; middle?
@LarrySabato: SNL will have to devote entire show just to Biden's facial expressions.
@TheFix: Ok. I have decided. I find the Biden smile slightly unsettling. #vpdebate
@JBarro: Biden smirk is... not good.
@TheFix: I do think Biden is on the verge of condescending/body language here in his tone. #vpdebate
@mpoindc: Biden really has to rein in his mannerisms. #NBCPolitics
@ralstonreports: Biden's facial expressions guarantee he will have a talk show after his elected career, but may not be good for a debate.
@Bryan_Llenas: Looks like its Joe "the joker" Biden tonight. I guess aides told him don't look down--just smile! #VPdebate #Debate
@msynan Biden laughing at Ryan again
@MarcACaputo Did anyone tell Joe Biden about the perils of the split screen and the poker face it can require?
@betsymtp: Biden constant smiling is reminding me of Gore constant sighing in 2000. #nbcpolitics
@MarcACaputo: Did anyone tell Joe Biden about the perils of the split screen and the poker face it can require?
@hollybdc: I wonder how Obama folks are feeling about Biden's laughs and eye rolls
