Conservative candidate Rubio leading the moderate Crist

Marco Rubio has come from far back to take a commanding lead in the Senate primary race in Florida.

From the Wall Street Journal

Two polls released last week showed Mr. Rubio leading the governor by 18 percentage points in the August primary, a reversal from last summer, when the former Florida House speaker trailed Mr. Crist by 30 points.

The article notes President Obama's declining popularity has had an impact on the race:

Mr. Rubio's ascent coincides with a descent in Mr. Obama's popularity in the key electoral state. Forty-nine percent of Floridians disapproved of the president's job performance and 45% approved in a January poll by Quinnipiac University. In February 2009, 64% of Floridians approved and 23% disapproved.
