CT not having one is how the detestable neoliberal centrist and No Labels/Problem Solvers kingpin Joe Lieberman (a major rat-fucker of Obama and Dems in general for years), after losing the 2006 Democratic CT US Senate primary, was able to get back into the Senate by running as an independent.

snip
Because Connecticut was believed to be a Democratic stronghold, political analysts considered its Senate seat safe to remain Democratic, but Lieberman's continued support for conservative and Bush administration policies made him vulnerable to a Democratic primary challenger. Lieberman was criticized for a lack of commitment to the Democratic Party, opposition to affirmative action; his opposition to a Connecticut state law that would require Catholic hospitals to provide emergency contraception to rape victims, his membership in the bipartisan Gang of 14, his support of Florida Governor Jeb Bush's involvement in the Terri Schiavo case, his initial willingness to compromise on Social Security privatization, alliances with Republicans; and his attacks on other Democrats.
