[Not quite a trend yet, but this was supposedly unthinkable two weeks ago. Iowa seems to be having even more of a cascade effect than it did in 2004]

Gallup: Clinton-Obama tied nationally; Huckabee leads GOP
Sen. Hillary Rodham Clinton and Sen. Barack Obama each drew 33% of
the support from Democrats surveyed in its latest national poll,
Gallup just announced.
In mid-December, well before Obama won last Thursday's Democratic
caucuses in Iowa, Clinton held an 18-percentage point lead over him
in Gallup's survey -- 45% to 27%. The closest the two had been in a
previous Gallup poll: Clinton's 37% to Obama's 36% in early June.
John Edwards remains third in Gallup's polling of Democrats. His
support: 20%, vs. 15% in mid-December. At 20%, Edwards is at a new
high in Gallup's survey. He touched 19% last April.
On the Republican side, Gallup says Iowa caucuses winner Mike
Huckabee has jumped into a national lead for the first time. The
rundown: Huckabee, 25%; Rudy Giuliani, 20%; Sen. John McCain, 19%;
Fred Thompson, 12%; Mitt Romney, 9%; and Rep. Ron Paul, 4%.
The surveys of 423 "Republicans or Republican leaners" and 499
"Democrats or Democratic leaners" each have margins of error on all
results of +/- 5 percentage points. The polls were conducted
Friday-Sunday.
As we noted earlier, Rasmussen Reports said today that its daily
tracking poll showed Clinton's lead over Obama nearly gone and that
Huckabee had edged ahead among Republicans.
