Massachusetts Democrats Deval Patrick, Elizabeth Warren campaign amid 2020 speculation
Incumbent Democratic Sen. Elizabeth Warren is running for re-election in Massachusetts amid speculation that she is laying the groundwork for a 2020 presidential campaign. Also, the Bay State's former governor, Deval Patrick, recently hit the campaign trail in Texas to endorse fellow Democrat Colin Allred, who is a candidate in a highly competitive House race. Patrick may also throw his hat into the 2020 race. Politico reporter Lauren Dezenski joined CBSN to discuss the possible presidential candidates.
