Odds tilt towards GOP Senate

Over several months, the party has expanded its range of targeted seats, and the National Republican Senatorial Committee (NRSC) has helped defeat insurgents it didn’t want representing the GOP in the midterm elections.

This sober realization came to Democrats on Wednesday, as Tuesday night’s primary results showed they cannot count on Tea Party candidates upsetting more-electable incumbents.

And Democrats are increasingly realizing that President Obama’s approval rating will probably remain mired at 45 percent or lower until Election Day, giving Republicans ammo.

As their difficulties mounted, Senate Democrats met with the president at the White House on Wednesday evening.
