With just days to go until voters have their say in the Galway West and Dublin Central byelections, many have made up their minds on who they intend to support but other votes remain up for grabs. Here is a look at the issues that are coming up on the doorsteps.Galway WestThe cost of living: Though the constituency is split between city and rural areas, there is considerable overlap when it comes to this issue.For urban voters, energy bills and prices of food, goods and services top the agenda. On a canvass in Mervue, one woman told a group campaigning for Sinn Féin’s Mark Lohan she is only getting about half the groceries she did last year for the same spend.It is slightly different in the rural part of the constituency because so many commute to the city by car. There has been a lot of discussion about the cost of diesel and petrol given Co Galway’s heavy dependence on cars for transport. A recent Government package, which reduced fuel prices by some 30 cent per litre, has helped to take the sting out of the issue somewhat, but for city and rural voters the cost of home heating oil remains a big concern.Tractors and trucks prepare to leave O'Connell Street last month after protests over fuel prices brought parts of the city to a standstill.

Government candidates have emphasised the impact of the Croí Cónaithe scheme, which offers grants to those renovating derelict properties, which has had a significant uptake here. In the city, a lack of affordable student accommodation has been a recurring topic. In Connemara, families are being refused planning permission because they do not meet the threshold of “local need” despite being from the area and native Irish speakers. Hundreds of houses along the west coast are offered as holiday lets and Government candidates (and those on the left) have been divided over whether these should reassigned to help meet long-term housing needs. Those defending their use for short-term stays say there would be a big loss of income in tourism dependent areas were this to change.

An Coimisiún Pleanála’s decision to approve a new outer ring road for the city has taken some of the heat out of the topic.Nevertheless, Galway city remains heavily snarled with traffic. There are frequent complaints about the lack of public transport and the shortage of cycle lanes. However, some residents complain about the impact new bike lanes are having on other modes of transport. There have also been calls in Galway for a light-rail system, similar to a smaller version of the Luas, to be built.In rural areas, the main issue is the condition of the road network, particularly potholes along the thousands of kilometres of minor roads in this vast constituency.Immigration: This issue has not been as dominant in Galway West as it might be in some other constituencies. That said, all the candidates say voters have raised concerns about immigration and asylum seekers with them. In some ways, the issue has defined the campaign of Independent Ireland candidate Noel Thomas, who has taken a firm stance in opposing accommodation for asylum seekers. This issue is expected to influence transfer patterns, which could have a bearing on the outcome.Independent Ireland's Noel Thomas canvassing on Eyre Square. Photograph: Alan Betson
