(CNN) - It's all tied up in Texas.
A new CNN/Opinion Research Corporation poll suggests that the battle for the Democratic presidential nomination between Sens. Hillary Clinton of New York and Barack Obama of Illinois is a statistical dead heat in Texas, which holds primaries March 4.
In the survey, out Monday, 50 percent of likely Democratic primary voters support Clinton as their choice for the party's nominee, with 48 percent backing Obama. But if you take into account the poll's sampling error of 4.5 percentage points for Democratic respondents, the race is a virtual tie.
Two recent polls by other organizations also show the race statistically even.
