From Fox News:
The Senate’s final verdict on Supreme Court nominee Brett Kavanaugh – whose high-stakes, high-wire confirmation hearing begins Tuesday – will hinge on the views of just a handful of lawmakers.
As it stands, Republicans hold a razor-thin, 50-49 majority with one vacancy. Arizona Republican Gov. Doug Ducey will soon appoint a successor to the late Sen. John McCain, R-Ariz., but even then the GOP majority can suffer few defections.
