Romney, Palin, Bachmann, Paul all drop since his entry

From Eric Dondero:

A super-interesting new compilation of polling figures from Nate Silver at the NY Times. Who's up, and who's down since Rick Perry's announcement for President. He writes:

Now there have been five surveys conducted since Rick Perry announced his presidential campaign — one each from Gallup, Rasmussen Reports and Public Policy Polling, and two from YouGov. Each shows Mr. Perry having vaulted into a lead over Mitt Romney.

Silver adds:

Mr. Perry’s results are yet more impressive if you account for his name recognition — which although increasing very rapidly remains behind that of Mr. Romney and some of the other Republican contenders.

Meanwhile, Gallup has Perry now firmly in the lead as the GOP frontrunner ahead of Romney 29% to 17%.
