(CNN) — It’s all tied up in Texas.

A new CNN/Opinion Research Corp. poll suggests 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 taking into account the poll’s sampling error of plus or minus 4½ percentage points for Democratic respondents, the race is a virtual tie.
