Tactical Voting against SDLP

This is our tactical voting guide to keeping out SDLP candidates in the 2029 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, considering the current forecast, they hold the constituency and are no more than 25 percentage points ahead of the second placed candidate or, alternatively, will not win the constituency and are 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 we forecast that the SDLP candidate will be so far behind that it appears they cannot win.
3. The third table contains the constituencies where we forecast that the SDLP candidate will be so far ahead that it appears they are unlikely to be beaten.

If a by-election has taken place after the last election and the boundaries have not changed, then that result is used instead of the one from the last election.

Usage Guide

In our 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.

Constituencies where tactical voting may help

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

Forecasted SDLP losses where we think they will be too far behind for tactical voting against them to be worth it

Our recommendation: Vote for whichever party you like.

Forecasted SDLP wins where we think their lead will be too large for tactical voting to make a difference

Our recommendation: Vote for whichever party you like.
