There will be lots of new polls this week trying to assess the effect of Donald Trump's conviction. But tomorrow, we could get a very different view on the matter. Three states will hold Republican primaries tomorrow: Montana, New Jersey, and New Mexico. Montana is a deep red state, but unfortunately (for us) it has open primaries so Democrats can vote there. New Jersey and New Mexico have closed primaries: Only Republicans can vote there. A question to which we will have an answer on Wednesday is: Will the vote for Nikki Haley and other non-Trump Republicans go up (or down) compared to primaries before the conviction? That could be interesting information if the results are different from the last few (closed) primaries. (V)
