A new Economist/YouGov poll is the third poll this week to show Rick Perry leading the Republican presidential field nationally.
Perry leads with 23%, followed by Mitt Romney at 15%, Ron Paul at 11%, Michele Bachmann at 9%, Herman Cain at 8% and Rudy Giuliani at 6%. All other candidates have less than 5% support.
Nate Silver: "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.
About two-thirds of Republican voters now recognize Mr. Perry's
name, which means that almost 4 in 10 who do recognize him have him as
their first choice, roughly double the fraction for Mr. Romney."
