Sen. Elizabeth Warren is running for re-election against Republican state Rep. Geoff Diehl and independent Shiva Ayyadurai. After Warren's comments last month that she would "take a hard look" at running for president after the November midterms, Diehl called on Warren to abandon her re-election campaign and drop out of the race.

Diehl joined Radio Boston to talk about why he believes she should drop out, as well as to discuss gun control, immigration, tax policy and escalating partisan rhetoric.
