Tactical Voting against SDLP

This is our tactical voting guide to keeping out SDLP candidates in the 2024 general election. This page takes the set of constituencies where SDLP candidates stood last time and divides them into three categories using the rules below.

Rules

We assume that tactical voting is only a good idea against a SDLP candidate in a particular constituency when, in the last election, they held the constituency and were no more than 25 percentage points ahead of the second placed candidate or did not win the constituency and were no more than 25 percentage points behind the winning candidate.

  1. The first table contains the constituencies which meet the above criteria.
  2. The second table contains the constituencies where the previous SDLP candidate was so far behind that it appears they cannot win.
  3. The third table contains the constituencies where the previous SDLP candidate was so far ahead that it appears they are unlikely to be beaten.

If a by-election has taken place after the last election then that result is used instead of the one from the last election.

Usage Guide

In my opinion, the best way of using this guide is as follows:

  1. Pick the name of a constituency.
  2. Find which table the constituency is in.
  3. Check the recommended advice above the table.
  4. Open the link to your selected constituency and verify whether our advised tactical vote seems plausible to you.

Our recommendation: Vote for the parties recommended in this table. If there are two such parties, the first choice is probably the most effective.
