Real estate mogul Donald Trump is tied for first in the race for the 2012 Republican presidential nomination, according to a new poll of Republicans. Nineteen percent of Republicans named Trump, who is flirting with a run for the party's presidential nomination, as their top choice for the nomination, according to a CNN/Opinion Research poll released Tuesday. Another 13 percent said Trump was their second choice in a nominee. SNIP Trump scored 10 percent in last month's CNN poll, meaning he effectively doubled his support over the course of a month.
