Since the 2012 round of congressional redistricting, Republicans had held a narrow enrollment advantage in the battleground 19th congressional district.

Not anymore.

Updated Board of Elections statistics for the Hudson Valley House district show Democrats with a very small enrollment edge over Republican voters. The Democratic gains come as Republican John Faso and Democrat Zephyr Teachout are locked in a hotly contested and costly race to replace Republican Rep. Chris Gibson in the House of Representatives.

Polls have shown Teachout and Faso in a virtual tie.

Back in 2012, Republican enrollment stood at 140,709 compared to 132,770 enrolled Democrats. Two years later, Democratic enrollment actually declined to 129,337.

But as of Nov. 1, Democrats now out number Republicans in the district: 137,821 to 137,656.

Still, it’s not a completely liberal advantage. Conservative Party enrollment has gained in the district from 10,471 in 2012 to 10,845 as of Tuesday.

Overall, left-leaning parties (Democratic, Working Families, Green, Women’s Equality) are still slightly outnumbered, with 32.5 percent of voters registered in one of those parties compared to 33.9 percent of voters registered as either Republicans or Conservatives.
