A bill seeking to require party registration in order to vote in Tennessee primaries is advancing the House. The bill sponsored by Rep. Andy Holt (R-Dresden) advanced on a voice vote in the Elections & Campaign Finance Subcommittee on Wednesday morning.

When Democrats sought to close primaries after soaring to new heights in the aftermath of the Watergate scandal of the mid-1970s, Republicans cried foul and the measure was defeated. This time, the roles are reversed, though the fate of this year’s measure remains uncertain.

Then-Gov. Ray Blanton and the Democratic State Executive Committee sought to cement their gains by imposing party registration rules for voting in primaries in the 1970s. Closing primaries, the argument went, would give the liberal wing of the party more sway by excluding Republicans and independents from influencing the nomination process.

Those efforts were thwarted by a coalition of Republicans and conservative Democrats from rural West Tennessee led by House Speaker Ned McWherter of Dresden and Senate Speaker John Wilder of Mason.

House Minority Leader Tom Jensen (R-Knoxville), who died last year year, said at the time Tennesseans had “made it clear they don’t want to be shackled with party registration laws.”

But times have changed. The Republican State Executive Committee in December recommended lawmakers enact party registration requirements in Tennessee.

Former Republican Gov. Bill Haslam called closing primaries “a silly proposal, ” arguing that if the change had been made earlier, it would have been much harder for Republicans to get to the position of power they’re in today. Gov. Bill Lee, who won the Republican nomination amid record turnout in last year’s  gubernatorial primary, was similarly dubious about the proposal, telling reporters that “the current system we have is working.”

Republicans today hold an even stronger position in state politics than Democrats did after Watergate. The GOP controls 73 of 99 seats in the state House and 28 of 33 in the state Senate, seven of nine seats in the U.S. House, and both U.S. Senate seats.

Under current state law, anyone can vote in a party primary if they are “a bona fide member of and affiliated with the political party.” The law also permits primary voting if “the voter declares allegiance to the political party in whose primary the voter seeks to vote and states that the voter intends to affiliate with that party.” The law has been interpreted to mean that seeking a party ballot is a declaration of allegiance.

In practice, many Tennesseans choose to vote in whichever primary is more compelling, meaning their allegiance and affiliation may last for as little as a single election.

Supporters of closed primaries argue that under the current system, crossover voters could help a weaker candidate win the nomination, who would then have a harder time prevailing in the general election. Another refrain is that open primaries give moderate candidates a better chance of winning primaries.

Nine states have closed primary systems, according to the National Conference of State Legislatures. Another seven have what the organization calls “partially closed” systems in which parties can choose whether to allow independent or voters registered with other parties to participate in primaries on a case-by-case basis.

NCSL counts Tennessee among six states with “partially open” primaries, where affiliation can be changed from election to election. Another 24 states are either fully open or allow independent voters to participate in the primary of their preference.
