Nervous Republicans focus energy on protecting Senate "firewall"

“If we lose the presidency – and if I had to guess right now, the odds are 10 percent we get the House back – the Senate is the only check and balance,” said one former Republican Senate chief of staff. “If we don’t keep the Senate, we’re basically screwed. I hate to just cut to the chase, but that is exactly what the [National Republican Senatorial Committee] is running with.”

Senate Republicans have relished their power to sideline major Democratic bills passed by the House, including sweeping election reform and gun legislation.

They argue that maintaining a GOP majority in the Senate is a crucial failsafe against “socialist” policies – the Green New Deal and “Medicare for All” – that could be pursued by a Democrat in the Oval Office coupled with a Democratic-controlled House.
