Depends on the ideology. A Democrat is going to be convinced that it's the Republican's fault, and a Republican is going to be convinced that it's the Democrat's fault. Simple as that. Kids.
Trump wanted a compromise on the whole issue, he wanted to finance DACA whiles the Democrat agree on the funding the Wall but the Democrats were not listening and in the end it brought about the shutdown, the democrats choose illegal immigrants over the citizens of the USA.
