Blue-leaning state emerges as top GOP trouble spot as Senate campaign chief sounds midterm alarm

The Senate Republican campaign chair has a stark warning for his party as the GOP defends its 53-47 majority in the chamber in this year's midterm elections.

National Republican Senatorial Committee (NRSC) Chair Tim Scott pointed to a ballot box deficit the GOP's facing in a new Fox News national poll, saying it could impact specific Senate races this year.

And Scott said the toughest challenge may be in Maine, where longtime GOP Sen. Susan Collins is running for re-election in the blue-leaning northern New England state.
