Rather than their policies for the upcoming election in one month, the first link in their header is an invitation to 'Meet Boris', which actually consists of a letter from him and what appears to be his CV (and a rather selective one at that):
To be fair, there are four rather concrete policies that the Conservatives want to push; safer streets, a stronger economy, better schools and more money for the NHS (as well as Brexit, obviously). Compared to certain other parties, that's refreshingly simple.
However, I'm not convinced. Without doing a deep dive, lets look briefly at each:
Police: The Tories want to make streets safer by hiring 20,000 more police officers. The big assumption here is that adding 20,000 more police to the streets (about 17% more officers than today) will make the UK's streets safe.
I think that's a stretch; frontline policing on it's own won't solve London's knife crime problem, the 'county lines' drug running gangs, human trafficking, or any of the other issues that this policy implicitly aims to tackle. They all require a broad and holistic approach, across many sectors and services to prevent the causes of crime, rather than simply more bobbies on the beat to catch people in the act.
Economy: I wrote about this above, but a vote for the Tories is a vote for consistency with the last ten years when it comes to the economy. This amounts to the 'safe option' when it comes to GDP, but a very iffy option when it comes to how that wealth is distributed among the population. After all, maybe reducing inequality would reduce the need for 20,000 more police.
Schools: Most of the parties in this election have 'better schools' on their agenda, I don't think the Tories really differentiate themselves there.
The NHS: All of the parties are scrambling to make (somewhat questionably hyped) claims about how they'll fund the NHS, I don't think the Tories differentiate themselves here either.
To sum up, I can think of two good reasons to vote for the Conservatives; if you want a hard Brexit like they're going for and aren't perturbed by how they've handled it so far, or if you simply are happy with how the country has been governed over the last ten years, and want that to continue.
I think a lot of the Tory approach to the election revolves around the charisma and character of Boris Johnson, which would be excusable, if they had the policies to back it up, but as said above, that doesn't seem to be the case.
Finally, I do think that the Conservative Party has played a large role in bringing about the Brexit crisis, something that has been hugely destructive, damaging, and embarrassing for the nation. In my view, that heavily weighs against them going into the next general election.
