My article on Monday: “The list of UK politicians most likely to be making up facts.” was pretty popular, which was nice. It was actually popular enough that I decided to repeat the process, except instead of using UK MPs I’ve used members of the US senate. I’m publishing the results in full here.

For those new to the post – I’ve writen some code that fetches a Twitter account’s recent tweets, strips out the retweets and also anything that doesn’t contain a number. I then compare the number of times the account tweets a number without a link. I’m NOT interested in who is right on any given issue, I’m interested in raising the level of the debate a little bit. I’m aware there are some weaknesses in the methodology and I discus them in this post.

Before I give the table, a couple of things surprised me. One was that US senators are, despite their reputation for partisan bickering as much much more likely to cite sources than the UK MPs. I had 15 MPs who hadn’t cited a single figure in the data on Monday. Today I have none. Plus the averages are a lot higher – all but two Senators cite more often than a full half of UK MPs. From a quick perusal it appears likely that this is due to US Senators being much more likely to have a dedicated press office, but that’s a bit of a wild guess.

In any case, here is the full list of US senators and how likely they are to reference figures they tweet about:

I should say, in defence of Senator Grassley, he has a lot of Tweets of this form:

UNI volleyball is serious 4me but to those of u who vomit abt those tweets here r FACTS:income inequality Read WStJ 11/12 Gramm/Solon oped — ChuckGrassley (@ChuckGrassley) November 15, 2014

where he shortens things like ‘for’ into ‘4’ and a very large number of tweets that appear to be reporting volleyball scores, which take down his average somewhat… still the odd link would be useful to see from him.
