I wouldn't say that would be a factor to win or lose a next election, just because an election has never been about gun control (I/we just don't know). Attention is always diverted or pulled towards immigration, the economy, infrastructure,...
After Parkland, it seemed the momentum was there to keep gun safety on the agenda, but it fizzled out. I'm not sure, but I think I have seen gun safety always being in the top 10 concerns, but never top 3-5.
Edit: found a graph to support my last sentence. Gun control is not a priority issue according to this.
