The Race for Control of the Senate and the "Trump Effect"

Donald Trump's march to the White House may have riled the Republican establishment, but it's giving Democrats fresh hope that they can reclaim control of the Senate in November. With 34 seats up for grabs – 24 of them now held by Republicans -- Democrats need a net gain of just five to regain control of the chamber. Seven of those are especially at risk, because they're in states that Barack Obama won in 2008 and 2012. The Senate Republican leadership's refusal to grant even a hearing to Judge Merrick Garland, Obama's nominee for the Supreme Court, is adding fuel to the fire. Will Republicans pay a price for balking on the High Court? Will Trump be an albatross that sinks the rest of the GOP? We hear how his surprising success is threatening Republican Senators from Illinois and Wisconsin to Pennsylvania and New Hampshire.
