Poll: Mitt Romney Has Significant Lead

Some numbers from the latest New York Times/CBS News polling:
...Mitt Romney has opened up a statistically significant lead among Republican primary voters across the nation trying to decide who should represent their party in this year's presidential election, but it's still a fluid race.

Romney gets 28 percent support among a fractured field of candidates, with Newt Gingrich in second with 21 percent, and Rick Santorum and Ron Paul (each coming off a strong early-state showings) nearly tied for third place with 16 and 15 percent, respectively.
Most surprising to me is that Mitt Romney and Newt Gingrich are doing so well with respondents who align themselves with the Tea Party.

Also notable, now that Huntsman is out of the race for the Republican nomination, Rick Perry is polling in last place at a dismal seven percent. His fall in polling has been dramatic. So much so that TPM has a page dedicated to "things that are less steep than Rick Perry's drop in the polls".
