Attorney and U.S. Marines veteran John Deaton has won the Republican primary for U.S. Senate. 

Deaton easily defeated industrial engineer Bob Antonellis and Quincy City Councilor Ian Cain in yesterday's primary. 

Deaton will now face two term incumbent Democratic Senator Elizabeth Warren in the general election in November. 

He moved to Massachusetts from Rhode Island last year, and largely has used his own wealth to fund his campaign.
