Mitt Romney's performance at the Republican National Convention in Tampa last week doesn't appear to be moving the needle in his favor:

  • Gallup finds Romney's speech producing the least impact in voters' intentions of any nominee's convention speech since 1984. Romney's speech also got the lowest "excellent" and "good" ratings since 1996.
  • Public Policy Polling finds holding the convention in Florida didn't boost Romney there: post-convention, Floridians still give Obama the edge, 48% to 47%.
  • PPP finds Obama leading Romney in his home state of Michigan 51% to 44%. 57% of those polled don't consider Romney a Michigander. Among Michigan Independents, 36% say the GOP convention made them less likely to vote Republican, while 25% said it made them more likely to vote GOP.
  • PPP finds Romney has pulled 3 points closer to Obama in Colorado. The President is holding steady at 49% in Colorado, while Romney has risen from 43% to 46%. PPP says Romney has firmed up his GOP base, but the President maintains a consistent lead among Independents.

Perhaps Mitt Romney is not seeing a bounce because he's mired in his own fibbery. Consider: Gordon Howie is shouting this morning about President Obama lying his way to a second term. Howie bases his sloppy, hyperbolic argument on Obama advisor David Axelrod's job creation claims. We can have a fair debate about how many jobs the President has created and about which month we should start counting at.

But to say the President is lying about job creation is an exaggeration exposing what seems to be an all too common GOP tactic: accuse the Democrats of exactly the sin Republicans are committing. To wit: Steve Benen is documenting the lies told by the Mitt Romney campaign. Over 30 weeks, Benen has documented 533 lies from Mitt Romney.

533 to 1—if Romney keeps lying at that rate, that's the Electoral College margin he'll hand to President Obama.

It's kind of hard to bounce, Mitt, when you're stuck in the mud of deception.
