Registered Republicans and Democrats are choosing their parties' standard-bearers for the November general election.
That includes primaries on Tuesday for candidates in two hotly contested races for the U.S. Senate and U.S. House of Representatives.
This marks the second time in two years that Connecticut has had an open seat for the U.S. Senate. Sen. Joe Lieberman, an independent, is retiring at the end of the year. Back in 2010, former Democratic Sen. Christopher Dodd did not run.
Former wrestling executive Linda McMahon is facing off against former U.S. Rep. Christopher Shays for the Republican Senate nomination. Meanwhile, U.S. Rep. Chris Murphy is up against former Secretary of the State Susan Bysiewicz (BY'-suh-wits) for the Democratic nod.
There are three Democrats and four Republicans vying for Murphy's 5th District seat.
