WEST PALM BEACH, Fla. — How can a wildly expensive Senate campaign be an undercard?

Apparently, when you have an open-seat race for governor with a quickly emerging Democratic star running against a former congressman aligned with President Donald Trump.

Two election-eve polls show the Democrats in both the gubernatorial and Senate races running ahead. A new NBC News-Marist poll has the Democratic candidates for each office up by four percentage points, within the survey’s margin of error among likely voters.

Quinnipiac, meanwhile, released its latest Florida poll showing the Democrats ahead by seven points in each contest, well outside the poll’s margin of error.

The polling suggesting there will not be much crossover voting might be working to the particular advantage of Bill Nelson, the incumbent Democratic senator here.
